ESBE valves - technical features of devices

ESBE valves - varieties of devices used to adjust the liquid or gas when it is supplied from one pipe to another. The three-way type of valve is featured by the presence of three compounds that allow you to effectively redirect streams in the system, especially if hot and cold water is mixed.

Adjustment of the valves of this type Within one system can carry out a servo. This device needs to pay a few more attention.

Servo. This is a separate element in the system that controls the position of the valves. The servo is usually most accessible in procurement and easy to install, therefore it is most often used at.

According to structural features, the servo can be different, most often in the category of such devices. For example, this can be installed with VRG131 samples. They give the highest quality and accuracy in maintaining the system, therefore are so great popular among consumers.

In some devices servo, as well as electric drive adjustment is not used. In such cases, such special devices are used as to adjust the operation of the equipment.

These species include, for example, the DN25 valve, which can be mounted into the tap without a drive.

Purpose of ESBE valves

This type of product can be used in a wide range of systems, including in heating systems, even centralized, hot, cold water supply, and air conditioning.

These types of valves for various systems are suitable, including working on petroleum products, gas, as well as eco-fuel, including solar energy or wind energy. You can set these types of equipment, for example, the three-way turning valve VRG131, both for central water supply networks and home networks.

You can choose a product for any crane. It is only important to choose the type of product correctly and install it according to the recommendations. Also for normal operation of the system is very important to adjust the servo or thermostatic regulator.

Then the model you chose will work without failures, regardless of the specified technical parameters.

Pros applying for this type of valve

Among the main advantages of the installation of ESBE products should be called:

Simplicity in the installation of this type of components, the ability to set samples actually into any system.
A wide temperature range of work, especially for models such as VRG131 rotary crane.
Universality in application - can be used in networks with different loads.
No need for maintenance of such samples with proper installation of such equipment.
Ability to use with any ESBE drive having the necessary specifications.
Presence in some details of the so-called burn protection functions - Automatic cessation of hot water supply in the event that the cold has ceased to flow into the system.

Popular ESBE Valve Models

Currently, such ESBE valve models are especially popular:

vTA200 equipment is the best crane for all water supply systems. Applicable for systems without recycling hot water, as well as HWCs that have such a function. Do not require special maintenance;
VTA270 - a model range applicable to installation in "Warm floor" systems. Can be mounted on systems where there is no risk of "burn". Suitable for systems with a rather large area - up to 100 square meters;
VTA310 - Equipment, like the VRG131 rotary crane, suitable for all water supply systems, in which there are no special requirements for burning burns. Designed for sections with the maximum temperature of the coolant 95 degrees, consider a differential pressure of 0.3 MPa. This type of valve can be mounted in a crane with any type of drive;
VTA330 / VTA360 - equipment that is installed in systems that do not have additional devices carrying out temperature control. Features of this equipment are that it, as well as a 3-way VRG131 crane, reacts as much as possible to changes in the pressure in the system and allows you to maintain a stable water temperature even with his jumps. This model comes with a special protective lid, unless, of course, the user has not chosen another complete set for itself. Details VTA330 / VTA360 are distinguishable only in the direction of water flows;

VTC300 - thermostatic mixer. The crane is used to install with boilers with a capacity of up to 30 kW. It is used in cases where the coolant is sufficiently low in the inverse tube of the equipment. There is no need to install a servo to this model - without it, it is also quite normally functioning. The equipment has several installation options and can be easily adapted to the requirements of the system you choose;
DN25 is another particularly popular valve model. Represents. Apply also to protect boilers Power up to 150kW. The operating temperature of this sample is also 110 degrees. DN25 is completely unpretentious to the installation conditions, its efficiency does not depend on the selected position of the installation;
model VRG131 - designed directly for use in hot water networks. VRG is released from the alloy of a specialized brass, which significantly increases its life. Can be installed manually. Recommended for the control of this three-way valve to use the servo drive of the same manufacturer.

Esbe products today enjoy large enough popularity. Not exception. It is one of the many elements that are included in the life support system of residential homes.

The need for use

This design, on the one hand, is quite simple, but on the other, it is designed to perform an extremely important task, being part of engineering networks. Everyone knows the rule that demand gives rise to a proposal, which is why there are many models in the market today, which are represented by all sorts of manufacturers. However, valves that are manufactured by ESBE are characterized by excellent performance indicators. The three-way valve of this type can be purchased at an affordable cost. This is confirmed by user feedback.

Constructive features

In a wide range today you can find ESBE products. The three-way valve is no exception. This element has an adjusting component, which is the ball or rod. The latter moves vertically, but as for the ball, his movement occurs around its axis. For the reason that the movement of the regulating element does not allow to overlap the fluid flow, the distribution and mixing occurs. The most ordinary and simple models are cranes.

Main Plus

The main advantage is low cost and simplicity. However, if you need an ESBE three-way valve adjustment, then it is necessary to eliminate the acquisition of simple devices, as they have the main disadvantage, expressed in the absence of the ability to perform the stabilization of the temperature regime at the output.

Conducting installation work

Almost all the valves described, which are presented on the market, are connected based on the same scheme. Most often, the faucet cranes are used in water supply systems. As the main goal, there is a decrease in the risk of the emergence of the reverse flow. A pressure drop will inevitably arise between cold and hot water streams. It can cause reverse flow. If you install the valve, then you will not encounter such a problem. If we are talking about the heating system, such devices are used exclusively in three directions, namely to stabilize the temperature of the coolant flow in the incoming pipeline of the boiler equipment, to reduce the water supply with high temperature from the heating device to the pipeline, as well as in the conditions of mixing nodes of systems By type a warm floor.

Connection in the mixing unit

If you are interested in ESBE products, a three-way valve can be purchased in any store of the respective goods. It is only before it to consider how the tap is used in the system a warm floor. The use of the mixing unit allows you to create an additional circuit in the system. Two points it is connected to this makes it possible to provide a permanent circulation of water at the output. As for the entrance, the flow is ensured solely if there is a need to get additional heat. The valve with the thermostat is attached to the mixing site. For the reason that all valves are located at the point, they are ejected, which can cause insufficient flow of pumping equipment. To increase it, you need to create an additional line, with which you can reduce electricity consumption by the pump. In the process of installing, it is worth remembering that the second line is not always required. A number of valve models has a fairly large pass. The ESBE three-way valve, the connection diagram of which can be developed on the basis of the instructions presented in the article may assume insufficient stream power on the first line. In this case, the thermostat does not have the ability to open the passage of the required value. This question can be easily solved in two ways: the first one implies the sequestment of the second line, while another option is to install on it the last option is considered more productive, since it allows you to adjust the stream.

Alternative installation option

Installation of the three-way ESBE valve can be made on another technique. It does not imply the use of balancing crane. The pump connects to the second line, ultimately the temperature of the output and input stream is equal. The tap with the thermostat is in systems with one contour. The most simple example of such systems is warm floors in small rooms. In this case, the creation of a mixing unit with large dimensions is not always justified. It will be best to connect a warm floor system with a single circuit. If you think about how to connect the ESBE three-way valve with an electric drive, then it can be placed on the return on which the cooled water runs. At the same time, the thermostat will lead to the movement of the shut-off reinforcement, the cross section will be increased, and the flow will turn out to be open. As soon as the pipe is heated, the thermal sensor will determine this and reduce the flow.

Installation of valve for boiler heating

This question, according to professionals, must be considered separately. The main task of the installation is to exclude the flow of cold water flow to the incoming pipeline, which is connected to heating equipment. If you do not consider this requirement, condensate will occur on the pipes, the temperature differences will result in deformation at the points of the joints. If we talk about the consequences of deformation, then at best you will come across a small flow, whereas in the worst system will be fully changed. In order not to need to repair the three-way ESBE valve, it is important to connect the shut-off valve to the boiler, which is characterized by temperature drops during operation. If you install a mixing valve, then you can achieve the fact that water does not come to the equipment, the temperature of which is below 50 degrees. The temperature difference is significantly reduced, the negative impact of the cold decreases. Specialists advise to complement systems that are equipped with the use of plastic pipelines, mixing valves. In this case, the task is to exclude in the pipeline of water with a high temperature. Despite the fact that polymers have many advantages, they do not well cope with frequent drops of temperatures that may be above the workers.

When exposed to such conditions, the pipeline system soon fails. Specialists advise you to choose ESBE products. The three-way valve, the installation instructions of which is presented in the article, is manufactured by this company for a long time. If you use this element, then you can provide temperature indicators ranging from 75 to 85 degrees that are recommended specialists. The installation of the valve allows you to cope with many problems, however, the model must necessarily be selected in accordance with the characteristics of the network, and also have a sufficiently large pass.

Features adjustment

By purchasing ESBE products - a three-way valve, the installation and adjustment instructions are presented in the article - you must remember that with this device, it is possible to make mixing of cooled water from the return to the feed. For high-quality regulation, it is installed on the system not only three-way, but also a four-way valve that should be present in the heating system. It is placed immediately in front of the floor circuit. The handle allows you to open bypass, with the circulation pumps and equipment tighten the cooled coolant from the return, where it is mixed with hot water. In order for the adjustment to be made as efficiently as possible, it should be sorted out what happens at certain positions of the handle. The latter can be set to the position of the bypass overlap, while the hot heat carrier will enter the pipe heating system of the warm floor. As for the regime, in which the feed is overlapped, water enters the tank and runs on a small circle. The third position allows you to feed the flow from the return system, without overlapping a full-fledged water flow cycle throughout the contour.

Conclusion

Experts recently are increasingly recommended to acquire the products of the ESBE brand. The three-way valve, the instruction, the electrical stroke of which are presented in the article, just an example. It can act as an indispensable element of the heating system and part of the boiler equipment, but it is important to choose the right model and make a setup, observing technology.

The three-way valve in the water supply system or heating is responsible for mixing or separating liquids of different temperatures, as well as to obtain the required temperature at the fluid outlet (adjustment of the coolant temperature applying a servo).

Design features

The device body contains two input and one outlet for fluids and a regulating element, which can be of different designs (for example, a rotary ball or running rod), also a place for a servo.

Usually, the valve is not intended to completely block the output flow of the fluid, but is able to only control the proportions of mixing liquids and the temperature in the system. The instruction does not assume, but functionally, overlapping the fluid supply is quite possible.

The three-way valve of a certain variety that performs separation functions may have a swivel servo to redirect the flow to different pipes (then it is called "shut-off").

In this case, the gradual or smooth mixing of fluids with temperature control does not occur, and the swivel mechanism itself consists of a ball (like a bughatti ball valve).

There are several types of its varieties, according to the type of drive mechanism performing the same functions:

Hydraulic rotary drive;
Pneumatic drive;
Electric servo.

So, three esbe's dove valve Having a servo, will assume the role itself and compatible with it drive production of the same company.

Views and differences

The EASB company leads its activities over a hundred years and specializes in temperature control for hydraulic systems of small buildings.

It produces a valve and a swivel servo for cooling or heating systems, also working "in bundles" with the sensors of the inner and outdoor temperature in the system. The principle of operation of the three-way ESBE valve is similar to the above options.

The company produces several model series of three-way valves, including a mixing valve:

Rotary valves (models of series: VRG130, VRG330, 3F, H, VRH130, HG);
Linear valves (series models: VLF300, VLF200, VLE132);
Thermostatic mixing valve (series models: VTA and VTS).

Rotary valves

VRG130 series valves are used for hot / cold water supply systems. In this model range, as in the following, there are various options (for example, the three-way valve from ESBE VRG 131 also refers to this series and has a connection for servo).

They are compact mixing models from brass alloys designed to minimize leaks and with manual adjustment scale. The manual indicates that they are also compatible with automatic control systems and ESBE controllers that allow you to automate the valve operation.

The three-way valve of the EUB of this model series - comes with DN 15-50 sizes, pressure class - Pn 10, models options provide varieties with the inner (three-way mixing valve type ESBE model VRG131 with a drive connected), external thread

(Model VRG132), with a cape nut or compression fittings.

Three-way the Military Mixing Crane ESBE VRG330 series has similar qualities with respect to the previously described VRG131 series (DN 20-50, PN 10), but is designed specifically for working with large streams (KVS differences between the inputs of 60 percent).

It can also be equipped with compatible controllers and automatic control. Released with three types of connection: Inner thread, outdoor thread, rotating nut.

According to the ESBE specification, the 3F Rotary Mixing Valves are designed to work on heating and cooling systems.

ESBE controllers and automatic controlrs can also be used with them (three-way ESBE Crane model VRG131 with electric drive immediately not supplied, which allows you to choose the most convenient option of the company's products).

For convenience of mounting, a three-way ESBE 3F crane is marked with an adjusting scale on both sides. The valve body is made of cast iron, also the model comes with an adapter for the PN 6 flange pipe, models sizes - DN25-150.

The ESBE ESBE valve (DN25-40) and Hg (DN25-40) and Hg (DN25) is designed to be installed on a limited space.

This three-way control valve from ESBE is used only for heating systems and is specified for working with a boiler room (made of cast iron, a special "H" -d-shaped case). He also has an acceptable price.

As the main type of compound, both inner thread and its mixed type are used. Compatible with controllers and ESBE drives as VRG131.

The VRH130 series models are also "n"-like option, but from brass with pressure class Pn 10. This model is more versatile than the previous sample and can also be used in water supply systems, is produced with different width of the case.

Linear valves

The VLF300 series is a three-way mixing linear with DN 15-50 sizes.

This model range lenne from cast iron with spherical graphite and can be used with the working fluid of both cold / hot water and the composition of which contain non-freezing components (glycol, for example).

In the latter case, the sample should be equipped with a rod heater. Completed with a flange for PN 6 pipe. Models similar to those previously specified, VLF200 DN25 are characterized by a large working pressure up to 16 bar, (against 6 bar in the previously specified model range).

Models of Vle132 are made of bronze with DN 15-50 sizes. These are linear motorized valves, which also, as well as previously specified similar models, can use water with glycol as working fluids (compound - outer thread PN16), unlike the VRG131 series. Its price ranges from 140 to 350 euros.

All specified linear three-point valves are compatible with the ESBE controller and drive.

Thermostatic mixing valve

VTS520 / 550 - The manual indicates that the three-way valves are designed to work with hot water systems that are connected to the solar heating system. Its price begins from 150 euros.

A feature of this model range is that the three-way thermostatic crane ESBE comes with specialized burn protection, since the liquid circulating in the system is sufficiently high temperatures.

The three-way thermostatic mixing valve from ESBE with "burn protection" suggests a sensor that automatically shuts off the servo drive to the supply of hot water if cold water is not served.

The coolant, with which these models work - water (including drinking), coolant of closed systems is water with non-freezing components. Pressure class - Pn 10, the housing is made of brass, resistant to corrosion exposure, for example, VRG131 valve is not suitable for such a system.

VTA330 / 530 - The thermostatic mixing valve from the ESBE of this series is designed to work in household hot water supply systems, as well as in cranes or souls, when other temperature controls are not provided (VTA330), or - in household hot water systems with a large stream (VTA530). Its price is within 150 euros.

Also equipped with a system protection you are from burns. The pressure class PN 10 (material is brass, resistant to corrosion influences), is produced with an outer threaded compound, fittings or adapters.

VTA360 / 560 is a series similar to the previous one by execution, but equipped with a large number of fittings and connections. The instruction assumes that the three-way ESBE drive of this series should also be compatible with the specified company in the specification.

Representatives of the VTA320 / 520 series can be used both under conditions similar to the work modes of previous model ranges and in systems where other temperature control systems are present.

These valves are recommended for hot water circulation systems (HWC) or for the "Warm Paul" system. Also equipped with "burn protection". VTA370 / 570 - Models intended for use in the "Warm Paul" system have a high bandwidth.

VTA310 is a sample that comes with an adjusting handle without burn protection system. It is used in household water supply systems, including in the hot water supply system of a closed cycle (HWC). The price of it starts from 50 euros.

Mounting and price features

When installing a three-way mixing valve, choose various options, instructions and algorithms for which installation is made. As a rule, the part is not installed directly to the heat source, since the system uses a non-barrier or "hydraulic arrow".

In an option for heating, a simplified instruction involves supplying the coolant from the boiler to the valve, from there the coolant is supplied to the heating system through the pump.

The liquid that has passed the heating system and cooled - is sent to the boiler for heating, but also to a mixing valve than the temperature control of the supplied substance is ensured.

The instruction for the ESBE three-way valve usually involves a description of the valve connection into the system, which, depending on the model range, may be different.

The three-way CW602N ESBE crane (here is the brand of brass) of the VRG130 model range (namely, VRG131 ½) is on average 170 dollars (if you get complete with a drive).

The price of a three-way valve from ESBE Linear VLA330, depending on the configuration, is 150 dollars (not equipped with an electrical drive).

The price of a three-way thermostatic valve ESBE (VTA 320) is possible for $ 70 and more.

Despite the simple design, the three-way ESBE valve refers to the number of those elements from which the life support is directly dependent. Adaptations of this type are available in several varieties.

general information

The three-way valve is a device for adjusting pipeline networks with a liquid working medium. If you explain popular, after switching on the heating system, the device will perform the function of a well-known faucet, whose task is to switch or mix flow.

Thanks to the three-way valve, the ESBE reached the following results:

Redirect flows from different networks.
The working fluid is provided to the necessary temperature indicator using the mixing of cold and hot liquids.
Dynamic redirection makes it possible to obtain a stream of stable temperature.

Features of the design of the three-way valve ESBE

Adjusting the three-way valve is carried out using a rod or ball. In the first case, the adjustment element moves in the vertical direction, in the second - around its axis. This element moves in such a way that the complete overlapping of the flow of the working fluid does not occur: it is only mixed and redirected. The simplest example of such a device is the usual crane. Its strong side is a simple design and low cost; Weak is the impossibility of obtaining a stable outlet temperature. With all its shortcomings, the cranes are widely used in the "Warm floor" systems.

If you enter an electrical drive into the design of a conventional crane, then it will be possible to significantly increase its functionality: the device will be able to adjust the temperature of the liquid medium in automatic mode. The task of simple balancing valves is to set the section under the flow of the workflow.

The operation of the device occurs as follows:

When the handle is turned halfway, two streams are evenly mixed, which is ensured by the equality of the inlet valves.
If you turn your handle to the end, press the first valve will occur, which is why the liquid flow completely overlaps.

In the sale of models of turns of the handles may differ slightly, which is not reflected in any way on the principle of operation of devices.

Main varieties

Three-way valves are three types:

Hydraulic drive.
Electric drive.
Pneumatic drive.

Electric appliances (for example, the ESBE model) differ slightly according to its principle of operation. The electric appendage acts here as a normal thermostat: thanks to it, the flows are not simply mixed, but also held in the desired temperature mode. During a decrease or increase in temperature, an automatic change in the position of the shut-off reinforcement is carried out. As a result, the flow cross section increases or decreases. In parallel, the section is changed at the cold flow entry section, which allows water to inform the outlet of the stable temperature. At the same time, the three-way ESBE valve is completely without monitoring human: the equipment is controlled on automation.

The ESBE valve with an electric and thermostat can be successfully used in heating systems and hot water supply. Strictly speaking, such a crane can be equipped with a pipeline of any type where two fluid flows need to be mixed and maintain a stable temperature. Even at the highest quality and reliable models of the three-way valve with a thermostat, there is one common drawback for products of this type: the input points through which the liquid flows is strongly narrowed. As a result, it provokes the growth of hydraulic resistance.

Such cranes are excellent for water supply. ESBE valves are often equipped with warm floors, although they use a special connection scheme. Along with the above-mentioned modifications, you can find three-way thermostatic valves. Despite the visible similarity of these devices, their functions are largely different. In thermostatic species, thermostats with a remote sensor are used. In addition, the principle of operation here is also different.

Unlike standard models, thermostatic cranes control the stream only at one point. Two other entrances are in a constantly open position, with a stable cross section. By purchasing such a design, it is important to test the second point for seeding, otherwise the complexity of the device may occur due to the large hydraulic resistance. If such a defect is detected, the problem can be solved by setting the mixing valve into an additional circuit.

ESBE Crane Connection Principle

For the overwhelming number of available three-way devices, one connection scheme is applied. For example, you can consider the installation of the three-way crane ESBE. It is better to start with a plumbing system where mixing cranes are most often found. Valves in this case prevent the formation of the reverse stream. The fact is that cold and hot streams have different pressure, which provokes the differences. As a result, the reverse flow may occur. ESBE valves are fully safe in this regard.

In heating systems, only three sections can be equipped with instruments:

Mixers of the "warm floor" system.
Included in the boiler tube. Thus, it is achieved to stabilize the temperature of the coolant in the incoming pipeline.
Exiting pipe, to reduce the supply of heated coolant.

Mixing knot

Application ESBE valve for a warm floor has its own specifics. The location of the mixing site is an additional contour. Switching with a collector-distributor is carried out by two points: This allows the coolant at the entrance to constantly circulate. The flow at the entrance is open only when the need for additional heat occurs.

The mixing unit commutes with a valve and thermostat. It should be understood that the thermostat for water underground can reduce the cost of heating. Considering the severity of all valves at point 2, the pump may face the problem of insufficient flow. To solve the problem, you need to live a second line that reduces the level of electricity consumption. But such a need does not always occur, because The cross section of some three-way valves is large enough.

In a situation where the first line has insufficient stream power, the overlapping of the thermostat of the passage does not occur on the desired scale.

To exit such a position, two options are usually applied:

The second line is shown.
Balancing valve is mounted.

The second method is more effective, because Flow is in this case more accurately. There is another ESBE three-way valve connection scheme for a warm floor - switching pump to the second line: here the balancing crane is not needed. This allows the level of temperature in the input and output stream.

Installation of the thermostat crane can be carried out in single-circuit systems. The most simple their variation is a warm floor of a small area. In this case, the overall mixing node is not very practical. A more appropriate solution will be the connection of a single-mate floor. The installation of a three-way valve with a thermostat is carried out on a inverse tube containing the cooled coolant. Thanks to the thermostat, shut-off valves, which increases the cross section. When the pipe heats up, the thermal sensor fixes it and reduces the stream.

Application of valves for heating boilers

Special attention deserves three-way valves for heating boilers. They perform a task to prevent the cooled coolant inwards entering the pipeline. If this is not done, the pipes will begin to be covered by condensate, and the system will arise a dangerous temperature difference. This is fraught with deformations of docking sites, the most harmless consequence of which will appear small leaks. If you do not react in time, the system can completely fail.

With a special responsibility, it should be referred to the installation of shut-off valves in the strapping of a solid fuel boiler, during which significant temperature differences occur (read also: ""). The mixing valve allows you to protect the boiler equipment from entering the coolant with a temperature below +50 degrees. Thus, the temperature difference is reduced, which favorably affects the efficiency and durability of the system.

Specialists recommend using mixing valves also in systems with a plastic pipeline. Although polymeric communications and have a number of advantages, however, the frequent excess of working temperature parameters act on them is destroying. According to regulations, the most comfortable temperature is in the range of + 75-85 degrees. Valves protect plastic pipes from many negative consequences. To the selection of the device model, it is necessary to consider responsibly, taking into account the technical characteristics of the engineering network.

The device body contains two input and one outlet for fluids and a regulating element, which can be of different designs (for example, a rotary ball or running rod), also a place for a servo.

Three-way valve with a servo for DHW

For many novice plumbers, there are many sacraments and riddles. In this article I will try to explain how to work with the servo drive of three different models. We will look at the logic of the work and the electrical connection scheme.

Option 1: Price from 6300 to 9200 rubles. There may be options for articles.

Option 2: Price about 2500-5000 rubles, if you try to find it on a Chinese site and order from China.

Option 3. Dear option, but there are a lot of options. The price may be about 15-20 thousand rubles.

Connection diagram of a three-way valve with servo drive for DHW

The valve can be installed both on the feed line (feed) and on the reverse line of the pipeline (reverse).

Many will ask the question: - And where better? On the feed or on the return?

According to the functional, the DHW is not fundamentally. But there are some nuances, why you need to put on the feed or on the return.

Nuances between feeding and reverse:

Anyone Does you know why you need to put a hydroaccumulator on the reverse line of the pump? Or believes that it can be put anywhere? Do you know why the pump is put on the feed or on the return? Answer: All because from where these elements are changing the pressure distribution at different points of the pipeline. And in some cases, again, it becomes convenient to pour and merge the heat carrier in the heating system. Also helps to avoid vesting and much more.

And why In the manual of boiler equipment recommend keeping the pressure of at least 1.5 bar? Because in the heat exchanger of the boiler you can not reduce the pressure! Reduced pressure leads to cavitation of the coolant in the heat exchanger. Also leads to early boiling of the coolant. And this all leads not only to lower the power of the boiler, but also the deposition of the scale in the heat exchangers, which leads to the deposition of scale and heat exchanger. Which in turn will lead to a small duration of the boiler equipment.

And you thinkIf a pressure gauge shows 1.5 bar, this means that the pressure is less than 1.5 BAR cannot be present in the system at the same height where the pressure gauge? Answer: This may be more often this happens at the owners who are independently invent, where the pump and the hydroaccumulator will stand. And do not understand how the pressure will be distributed after that.

Also, how the hydroaccumulator affects the pressure distribution: http://santeh-baza.ru/viewtopic.php?f\u003d2&t\u003d93

Why do you need a three-way valve for DHW?

The main task of the three-way valve for DHS is to redirect the movement of the coolant from the heating system towards the boiler of indirect heating (other heat exchanger) and back automatically.

As soon as the team came to heat the boiler of indirect heating, then you need to redirect the coolant towards the Zmeevik BKN. The heating signal is generated by a special relay, which is located at BKN (the boiler of indirect heating). That is, BKN has a built-in electric thermo relay, which gives the switch to the switch.

What does a three-way valve for DHW look like?

Electrical circuit with boiler and boiler

Servo Drive has three contacts one common. If you give a voltage of 220 volts to two contacts (direction 1 + total) will be one position. To another position, you need to give a voltage of 220 volts to another contact (direction 2 + total). Phase and zero network 220 volts are not fundamentally.

Option 3. The most difficult version that requires more detailed study. It has a variety of functionality of work.

If you have a more productive heating system + DHW with big expenses. That use valves of option 1 and 2 does not have the ability, as they have a small bandwidth!

This device consists of two parts:

1. Rotary mixing valve (diameter to choose from)

Servo ESBE.

Servo model: ESBE ARA641 by 220 volts. 30 seconds. Article number 12101100.

Drive characteristics:

1. Rotate 90 degrees. There is a deduction adjustment setting. You can make a little more or slightly shifted aside.

2. 3 Speakers. That is, 3 contacts 220 volts for control: Terminal 1, terminal 2 and a common terminal.

3. The time for which the drive turns 90 degrees depends on the model. Model ARA641 30 sec.

4. Cable wires 1.5 meters.

5. Torque force: 6 nm.

Electric servo diagram: ESBE ARA641

This device has three conductor: blue, brown and black.

Blue - Common guide, usually closed zero

Brown and black These are conductors of position 1 and 2.

When a 220 volt voltage is on blue and the black drive turns into one direction 90 degrees.

When the voltage is 220 volts on the blue and brown drive turns to the other side by 90 degrees.

Such servos have a button to turn off the direction of movement. That is, you can use the valve to the desired position during repair or test.

Pay attention, the more topics you may need torque.

In the eSBE catalog You can pick up other valves and servo drives!

For example,

1. Select not three-point (tripkontact) control, and two-point control. That is, one contact is constant voltage, and on the second contact you simply give or select the voltage.

2. The angle of rotation can be more than 90 degrees. For example, 180 degrees.

3. Closing time is not 30 seconds, but much more. For example, you may need a smooth transition to 1200 seconds.

4. Take a drive with another torque power.

5. Drive by 24 or 220 volts.

6. You can choose not only to switch, but also to obtain the desired temperature mixing.

Download the ESBE catalog For selection of valve and servo: esbekatal.pdf

If someone has a two-point signal from an indirect heating boiler or from some thermostat that has only two-point contact, then an electromagnetic switching relay can be used.

This model must be sought in specialized electricians and electronics stores.

Model: ABB CR-P230AC2. 220 volts are fed to contact 1 and 2. The load of switching contacts by 8 amps does not exceed. 8 A x 220 volts \u003d 1700 watts. It will endure equipment up to 1700 W. Not applicable to pumps and incandescent lamps as the first start requires high currents.

In order to connect it to the Wires, a special jack is used:

ABB CR-PLSX (logical) for the CR-P relay

The following should happen:

That's all right. Specify questions! Did you all understand? Maybe something is missing?

Three-way mixing valves (cranes, valves) and ESBE drives

The three-way valves of the ESBE are usually used as mixing valves, but can be used as switching or dividing. It is necessary to make sure that the nominal pressure, the pressure drop and the leakage value were within acceptable limits. This information is given to each valve.
Four-way valves are usually used when a high temperature of the coolant on the reverse is required (usually for solid fuel boilers). In systems with two heat sources or accumulation tank, the valves will help organize priority in using an inexpensive heat source, while maintaining good temperature separation in the accumulation tank.
Principle of operation of 3-run valves ESBE VRG130. The required temperature in the system is achieved with the addition of the addition of water from the reverse pipeline supplied to the boiler.

How does the ESBE three-way valve work?

The required temperature in the heating system is provided by proportional to add a colder coolant to a hotter coolant flow from the boiler.

How does the four-step valve work?

The valves of this type have a double mixing function, that is, a hotter coolant is mixed with a cooler coolant serving to the boiler. This allows you to raise the temperature of the coolant in the return on (returning to the boiler) and reduce the risk of low-temperature corrosion, the STR significantly prolongs the operation time of the boiler.

EXAMPLES OF INSTALLATION AND HYDRAULIC CHARACTERISTICS OF MACHINE VALVES ESBE series VRG and 3F

ESBE VRG.

ESBE 3F.

Principle of operation 3, 4, 5 running and bivalent mixing valves ESBE

Advantages of the mixture valves ESBE:

Easy to install drives.
Compact size, ease and ease of installation - during installation requires a minimum of tools.
Minimal dimensions of mixing valves facilitating installation in cramped conditions.
Reliable valve set with internal thread. The faces for the key wider and has two edges instead of six. It provides the best grip and a smaller risk of sliding a pipe key or a cape wrench.
More flexible cable connection. Drives are supplied with a connecting cable, as well as with an additional cable contact. The advantage is that it is possible to stretch a separate cable, for example, directly to the circulation pump without connecting via the central controller.
High control accuracy.
The minimum delay and high accuracy of the entire cycle, from full closure to the full opening of the valve, the valves provide the ability to use the full angle of rotation. Such adjustment is as close as possible to ideal and ensures improvement of comfort and reduced energy consumption.
ESBE valves are known for their minimal inner leaks, they are awarded the Prize "The best product of Plumbing Equipment 2003".
The leakage percentage is reduced from 0.1 to 0.05%. And this is achieved at double pressure, i.e. at 100 kPa (1.0 bar). The valve that provides more dense locking, it is difficult to find and buy in the turbid valve market.
Easy and convenient regulation, high performance
Reliable and have a long service life

What is KVS? Each mixing valve has a KVS characteristic (bandwidth M3 / h with a pressure loss of 1 bar). The KVS parameter helps determine which valve is necessary for your heating system. You can define the KVS valve ESBE according to the schedule below.

Select the size of the mixing valve by ESBE

Selection of mixing valves ESBE VRG and VRB series for an outdoor or radiator heating system.
We start from the heat power of the boiler in kW (for example 25 kW). Moving vertically to the selected temperature mode T (for example 15 ° C). Next, we move horizontally to the shaded area (the drop of pressure drop 3-15 kPa) and select the smaller KVS coefficient value (for example 4.0).
In this case, select the desired type of valve with the KVS \u003d 4.0 coefficient

The KVS value is accepted for the flow only in one direction.
For the 4-run valves, the dual value of the pressure drop P indicated on the graph.

The materials used, the requirements for the coolant.

VRG, VRB and 5MG series valves are made from a special brass alloy (DZR Dezincification Resistant Brass, CW 602N), which has advantages that cannot be achieved in structures that combine cast cast iron and brass. This allows them to use them for water supply systems with sanitary hot water.
Selective corrosion of brass (Zinc is released from ordinary brass, leaving a fragile, porous copper mass) is the most dangerous type of corrosion, leading to a rapid decrease in the life and reduction of functionality. Coating the inner surface of the valves and valves layer DZR reduces the likelihood of adhesion of pollution and precipitation to valves, What provides a decrease in wear and obtaining cleaner water. The alloy also contains less lead, compared with many other products. and especially suitable for installation of water supply water supply systems.
All other ESBE valves can be used only in closed systems with water that does not contain dissolved oxygen.
To protect against freezing, it is allowed to use a coolant with a glycol content and additives, neutralizing dissolved oxygen, a concentration of maximum to 50%. When it adds glycol to water, its viscosity increases and heat capacity changes, so it must be considered when choosing a valve. If the percentage of glycol is 30-50%, then in this case you need to select another valve with a large KV coefficient. Lower glycol content does not affect the valve action.
