Esbe valves - technical features of devices

Esbe valves are types of devices used to regulate a liquid or gas when it is supplied from one pipe to another. The three-way type of valves is distinguished by the presence of three connections, which effectively redirect the flows in the system, especially in the case of mixing hot and cold water.

Adjustment of the operation of valves of this type within the same system can carry out a servo drive. This device needs to be given a little more attention.

Servo. It is a separate element in the system that controls the position of the valves. A servo drive is usually the most affordable in the purchase and is easy to install, therefore it is it that is most often used when.

By design features, the servo drive can be different, most often they are included in the category of such devices. For example, this can be installed with vrg131 samples. Today they provide the highest quality and accuracy in servicing the system, which is why they are so popular among consumers.

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

These varieties include, for example, the dn25 valve, which can be mounted in a crane without a drive.

Purpose of Esbe valves

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

These types of valves are suitable for various systems, including those operating on oil products, gas, as well as eco-fuels, including solar energy or wind energy. It is possible to install these types of equipment, for example, the vrg131 three-way rotary valve, both for central water supply networks and for home networks.

You can pick up a product for any tap. It is only important to choose the right type of product and install it according to the recommendations. It is also very important to adjust the servo or thermostatic regulator for the normal operation of the system.

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

Advantages of using this particular type of valve

Among the main advantages of the installation of the Esbe products are:

Simplicity in the installation of this type of components, the ability to install samples in virtually any system.
Wide operating temperature range, especially for models such as the vrg131 slewing crane.
Versatility in application - can be used in networks with different loads.
No need for maintenance of such samples with the correct installation of such equipment.
Suitable for use with any Esbe actuator with the required specifications.
The presence in some of the details of the so-called scald protection functions- automatic interruption of hot water supply in the event that cold water ceases to flow into the system.

Popular Esbe Valve Models

Currently, the following Esbe valve models are especially popular on sale:

VTA200 equipment is the best tap for all water supply systems. Suitable for systems without hot water recirculation, as well as HWC with this function. No special maintenance required;
VTA270 is a model range suitable for installation in underfloor heating systems. They can be installed in systems where there is no risk of "burns". Suitable for systems with a fairly large area - up to 100 square meters;
VTA310 - equipment, like the vrg131 slewing valve, suitable for all water systems where there are no special requirements for protection against burns. Designed for areas with a maximum coolant temperature of 95 degrees, withstand a differential pressure of 0.3 MPa. This type of valve can be installed in a valve with any type of actuator;
VTA330 / VTA360 - equipment that is installed in systems that do not have additional devices that carry out temperature control. The peculiarities of this equipment are that it, like the 3-way valve vrg131, reacts as sensitively as possible to changes in pressure in the system and allows you to maintain a stable water temperature even during its surges. This model comes with a special protective cover, unless, of course, the user has chosen a different configuration for himself. The parts VTA330 / VTA360 are only distinguishable in the direction of the water flow;

VTC300 is a thermostatic mixer. The crane is used for installation with boilers up to 30 kW. It is used in cases when a coolant of a sufficiently low temperature is supplied through the return pipe of the equipment. There is no need to install a servo for this model - without it, it also functions quite normally. The equipment has several installation options and can be easily adapted to the requirements of your chosen system;
DN25 is another particularly popular valve model. Represents . Also suitable for boiler protection power up to 150 kW. The working temperature of this sample is also 110 degrees. DN25 is completely unpretentious to the installation conditions, its efficiency does not depend on the chosen installation position;
model vrg131 - designed directly for use in hot water networks. Released vrg from a specialized brass alloy, which significantly increases its service life. Can be installed manually. It is recommended to use a servo drive from the same manufacturer to control this three-way valve.

I provide passport data and video of the servo. I also show you how to connect and mount and then configure the servo for a three-way valve.
And so let's get started ...
In this article, we will look at the most versatile ESBE 99K2 servo drive, which is shown in the picture, and the ESBE VRG131 valve.
The actuator is sold with two connection kits, for two different standard 3-way valves with an unrestricted rotary valve. More details will be indicated both in the passport and on the video.
It is important to understand:
1. The three-way valve itself has a ball valve that rotates in a circular way for an unlimited rotation. For work, the valve must be turned clockwise and counterclockwise from 90-180 degrees of rotation.
2. A servo is an electrical equipment and device for rotating this ball valve. By rotating the valve, two passages are opened and closed, and the third one is permanently open. The servo drive, by means of a temperature sensor, drives the rotation in the desired direction to open or close the hot circulation line. More details on the video and in the passport. We also analyze how to set up a valve for a specific circuit.
ESBE 99K2 servo drive, advantages:

Power supply 220 Volts
Electrical remote temperature sensor
Temperature control (15-70 degrees) in real time
Adjustment of the time (1-70 seconds) for checking the temperature sensor and turning on the rotation.
Swing adjustment: 10-180 degrees
Switching clockwise and counterclockwise rotation (reverse)

At 90 degrees, it is possible to set the required rotation of the ball valve in real time for testing (press the button and scroll). If a 180 degree rotation is required, then the handle is not installed and adjustment cannot be made. And this is not necessary, the function is useful only for masters when testing the mixing unit.
Flaw: If there is no electricity, the valve does not return to any position, but freezes in the position in which it is set automatically.
And in general, it is used for large objects where it is necessary to make a mixing unit with a high flow rate (from 2 cubic meters per hour and above).

Despite its simple design, the esbe three-way valve is one of those elements on which the life support of the whole house directly depends. Devices of this type are available for sale in several varieties.

general information

A three-way valve is a device for regulating pipeline networks with a liquid working medium. To explain popularly, after being included in the heating system, the device will perform the function of a well-known mixer valve, the task of which is to switch or mix flows.

Thanks to the esbe three-way valve, the following results are achieved:

Redirecting streams from different networks.
The working fluid is brought to the required temperature indicator by mixing cold and hot fluid.
Dynamic redirection makes it possible to obtain a stream of stable temperature.

Design features of the ESBE three-way valve

The 3-way valve is adjusted using a stem or ball. In the first case, the adjusting element moves in the vertical direction, in the second - around its axis. This element moves in such a way that a complete shutdown of the flow of the working fluid does not occur: it only mixes and is redirected. The simplest example of such a device is a conventional crane. Its strong point is its simple design and low cost; weak - the inability to obtain a stable outlet temperature. For all their shortcomings, taps are widely used in underfloor heating systems.

If an electric drive is introduced into the design of a conventional tap, then it will be possible to significantly increase its functionality: the device will be able to regulate the temperature of the liquid medium in automatic mode. The task of simple balancing valves is to adjust the cross-section to the flow of the working flow.

The device works like this:

When the handle is turned in half, the two streams are evenly mixed, which is ensured by the equality of the inlet valves.
If you turn the handle all the way, the first valve will be pressed, due to which the liquid flow is completely blocked.

For commercially available models, the turns of the knobs may be slightly different, which in no way affects the principle of operation of the devices.

Main varieties

Three-way valves are of three types:

Hydraulic drive.
Electric drive.
Pneumatic.

Devices with an electric drive (eg model ESBE) differ slightly in their operating principle. The electrical appendage here acts like a regular thermostat: thanks to it, the flows are not only mixed, but also kept in the desired temperature regime. During a decrease or increase in temperature, the position of the shut-off valves is automatically changed. As a result, the flow cross section is increased or decreased. In parallel, there is a change in the cross-section at the inlet of the cold flow, which makes it possible to give the water at the outlet a stable temperature. In this case, the three-way ESB valve is completely dispensed with from human control: the control of the equipment falls on the automation.

The ESBE valve with electric drive and thermostat can be successfully used in heating systems and in hot water supply. Strictly speaking, such a valve can be equipped with any type of pipeline where it is required to mix two flows of liquid and maintain a stable temperature. Even the highest quality and most reliable models of a three-way valve with a thermostat have one common drawback for products of this type: the entry points through which the liquid enters are greatly narrowed. As a result, this provokes an increase in hydraulic resistance.

These taps are great for plumbing. ESBE dampers are often equipped with underfloor heating, although they use a special connection scheme. Along with the modifications mentioned above, three-way thermostatic valves can be found on the market. Despite the apparent similarity of these devices, their functions differ in many ways. In thermostatic varieties, thermostats with a remote-type sensor are used. In addition, the principle of operation is also different here.

Unlike standard models, thermostatic valves only control the flow at one point. The other two entrances are in a permanently open position with a stable cross-section. When purchasing such a design, it is important to test the second point for narrowing, otherwise difficulties may arise in the operation of the device due to the high hydraulic resistance. If such a defect is found, the problem can be solved by installing a mixing valve in an additional circuit.

ESBE crane connection principle

For the vast majority of commercially available three-way devices, one connection scheme is used. For example, consider the installation of an esbe three-way valve. It is best to start with the plumbing system, where mixing taps are most common. The valves in this case prevent the formation of a reverse flow. The fact is that cold and hot streams have different pressures, which provokes drops. As a result, reverse flow may occur. Systems with ESBE valves are completely safe in this respect.

In heating systems, only three sections can be equipped with devices of this type:

Mixers of the "warm floor" system.
Pipe entering the boiler. Thus, the stabilization of the temperature of the coolant in the incoming pipeline is achieved.
Outlet pipe, to reduce the supply of heated heating medium.

Mixing unit

The use of the esbe valve for underfloor heating has its own specifics. The location of the mixing unit is an additional circuit. The connection with the manifold-distributor is carried out through two points: this allows the coolant at the inlet to circulate constantly. The inlet flow is only opened when there is a need for additional heat.

The mixing unit is commutated with a valve and a thermostat. You need to understand that a thermostat for a water-heated floor allows you to reduce heating costs. Considering the narrowness of all valves at point 2, the pump may encounter an insufficient flow problem. To solve the problem, it is necessary to live a second line, which reduces the level of electricity consumption. But such a need does not always arise, since some three-way valves are large enough.

In a situation where the first line has insufficient flow capacity, the thermostat does not block the passage on the required scale.

To get out of this situation, two options are usually used:

The second line is narrowed.
A balancing valve is installed.

The second method is considered more effective, because the flow in this case is adjusted more precisely. There is another connection diagram for the esbe three-way valve for underfloor heating - switching the pump to the second line: a balancing valve is not needed here. This allows the temperature conditions in the input and output flow to be equalized.

Installation of a valve with a thermostat can be carried out in single-circuit systems. Their simplest variation is a warm floor of a small area. In this case, it is not very practical to use a large mixing unit. A more expedient solution would be to connect a single-circuit underfloor heating. The installation of a three-way valve with a thermostat is carried out on a return pipe containing a cooled coolant. Thanks to the thermostat, shut-off valves are activated, which increases the cross-section. When the pipe heats up, a thermal sensor detects this and reduces the flow.

Application of valves for heating boilers

Three-way valves for heating boilers deserve special attention. They perform the task of preventing the cooled coolant from entering the pipeline entering the boiler. If this is not done, the pipes will begin to become covered with condensation, and a dangerous temperature difference will develop in the system. This is fraught with deformations of the docking areas, the most harmless consequence of which will be the appearance of small leaks. If you do not react in time, the system can completely fail.

Particularly responsible should be taken to the installation of valves in the piping of a solid fuel boiler, during the operation of which there are significant temperature differences (read also: ""). The mixing valve allows you to protect the boiler equipment from the ingress of coolant inside it with a temperature below +50 degrees. In this way, a reduction in the temperature difference is achieved, which favorably affects the efficiency and durability of the system.

Experts recommend using mixing valves also in plastic piping systems. Although polymer communications have a number of advantages, the frequent excess of operating temperature parameters has a destructive effect on them. According to the standards, the most comfortable temperature regime is in the range of + 75-85 degrees. Valves protect plastic pipes from many negative effects. The selection of a device model must be taken responsibly, taking into account the technical characteristics of the utility network.

The ESBE three-way valve is just one of the elements of the life support systems of a residential building. On the one hand, this is a simple design. On the other hand, it performs an important task in engineering networks. Demand creates supply. There are many models on the market from different manufacturers. The ESBE brand three-way valves have good performance characteristics.

Some useful knowledge

ESBE 3-way rotary valve

The three-way valve is a regulating device in piping systems with a liquid working medium. In simple terms, built into the design of the heating network, it will act like everyone is familiar with - a mixer tap that switches or mixes flows. Installing the valve allows you to solve a number of practical problems:

Redirecting flows from different pipelines.
Achieving the desired temperature of the working fluid by mixing hot and cold streams.
Obtaining a constant temperature jet by dynamic redirection.

Hard? Only at first glance. In order to understand the principle of operation of the device, consider its design features.

Design

The three-way mixing valve has a control element, which is a stem or a ball. The stem moves vertically, the ball around its axis. Since the movement of the regulating element does not allow to completely shut off the flow of the working fluid, it is mixed and redistributed. The simplest models are a conventional crane. Their main advantage is their low cost and constructive simplicity. The disadvantage is the impossibility of stabilizing the outlet temperature. Despite the disadvantages, the tap can be installed in underfloor heating systems. Now imagine a motorized valve. This design is already more functional, since it is able to automatically regulate the temperature regime. A simple valve is a balancing valve. Its main function is to adjust the cross-section for the passage of the working stream. Conventionally, the principle of its operation can be described as follows:

The handle is turned 50% - even mixing of the two streams, since the inlet valves will be equal.
The handle is turned 100% - the first valve is fully compressed and closes the movement of the fluid flow.

The modifications presented on the market may have different turns of the handle, but the principle of their operation remains the same. The valve and its position are manually adjusted, thereby ensuring a balance between the two flows.

Kinds

There are several types of such devices:

Hydraulically driven.
With pneumatic drive.
Electrically operated.

An electrically operated three-way valve, such as the ESBE model, will have a slightly different operating principle. The electric drive performs the function of a conventional thermostat, which makes it possible not only to mix flows, but to maintain the set temperature. With a decrease / increase in temperature, the actuator automatically changes the position of the shut-off valves, increasing or decreasing the cross-section of the hot water flow. At the same time, the cross section at the inlet of the cold stream also changes. As a result, water with a constant temperature is obtained at the outlet. The ESBE crane does not require any human intervention. Its work is regulated by automation.

Valve principle

ESBE valves equipped with electric actuators and thermostats are equally well suited for use in heating and hot water systems. In principle, the valve can be installed in any pipeline where it is necessary to mix two liquid streams with constant temperature control. No matter how high-quality and reliable the three-way valve with a thermostat is, it will have one drawback, which is characteristic of absolutely all devices of this type.

Such a disadvantage is the strong narrowing of the entry points. The narrowed section of the entry point, in turn, increases the hydraulic resistance.

Such a faucet will work well in water supply systems. ESBE dampers are suitable for installation in underfloor heating systems, but a special wiring diagram is required. In addition to the designs described above, there are three-way thermostatic valves on the market. These devices are often confused with each other, but still they are completely different. Thermostatic models have a thermostat with a remote sensor, but they differ not only in this element, but also in the principle of operation. Unlike conventional models, in thermostatic valves, the flow is regulated only at one point, the two remaining ones are open, and their cross section does not change. When choosing such a design, you need to check if there is a narrowing at point 2, otherwise the hydraulic resistance will lead to difficulties in the operation of the device. You may need to install a mixing valve in an alternate ring to minimize the problem.

Connection diagrams

Three-way valve - connection diagram

Almost all three-way valves on the market are connected in the same way. Let's take a look at the example of ESBE cranes. Let's start with the water supply systems, since the mixer tap is used most often here. The main purpose for which the valve is installed is to reduce the risk of backflow.... A pressure drop will inevitably occur between the two streams - with cold and hot water. It can lead to reverse flow. When installing ESBE valves, such incidents are rare. In heating systems, ESBE valves are used in only three ways:

In mixing units for underfloor heating systems.
To stabilize the temperature of the liquid flow in the boiler inlet piping.
To reduce the supply of heat carrier with a high temperature from the boiler to the pipeline.

The valve in the mixing unit

Let's consider how the ESBE crane is used in underfloor heating systems. The mixing unit creates an additional circuit in the system. It is connected to the distribution manifold by two points, which ensures constant circulation of the liquid at the outlet. At the inlet, the flow is ensured only if additional heat is required. A valve with a thermostat is connected to the mixing unit. Since at point 2 all valves, including ESBE, are narrowed, insufficient pump flow may be observed. To increase it, a second line is being created, which makes it possible to reduce the consumption of electricity by pumping equipment. A second line is not always required. Some models of 3-way valves have ample bore.

Underfloor heating scheme with a three-way valve

In the event that there is insufficient flow power on the first line, the thermostat will not be able to open the passage to the required amount. . The problem can be easily solved in two ways: by narrowing the second line or by installing a balancing valve on it. The second way is more productive. It allows you to fine-tune the flow. It is possible to connect the three-way valve in a different way, which does not require the installation of a balancing valve. For this, the pumping equipment is connected to the second line. As a result, the temperatures of the inlet and outlet streams are compared. The thermostatic valve can be installed in systems with one circuit. The simplest example of such systems is underfloor heating in small rooms. Create a mixing unit here , with its considerable dimensions , is far from always justified. It is better to connect a warm floor with one circuit. A three-way valve with a thermostat is installed on the return line, through which the already cooled coolant flows. In this case, the thermostat will set in motion the shut-off valves, increasing the cross-section and opening the flow. After heating the pipe, the thermal sensor reads the data and reduces the flow.

For heating boilers

Three-way valves for heating boilers should be considered separately. The main task of their installation is to prevent a cold flow of the coolant to the incoming pipeline connected to the boiler. Otherwise, condensation will begin to form on the pipes, and temperature differences in the system will lead to its deformation at the joints. There is no need to talk about the consequences of such deformations. At best, a small leak is formed, at worst, the system will have to be completely changed.

Three-way valve in the heating system

It is especially important to connect shut-off valves to solid fuel boilers, which are characterized by significant temperature differences during operation. Connecting a mixing valve makes it possible to ensure that no liquid reaches the inlet of the boiler equipment, the temperature of which is below 50 degrees. As a result, the temperature difference decreases, the negative impact of cold, with all the ensuing consequences, decreases. Installation of mixing valves in plastic piping systems is recommended. Here, the goal is to prevent high temperatures from entering the coolant pipeline. With all the advantages of polymers, they do not withstand frequent increases in temperatures above operating parameters. In such operating conditions, the pipeline collapses quickly. The temperature ratings recommended by experts are in the range from 75 to 85 degrees. The installation of valves can solve many problems, but the model must be selected in strict accordance with the technical characteristics of the utility network, and must have a sufficient passage.

Conclusion

The simplest shut-off valves - three-way mixing valves - are an important element of engineering communications. Modern models, created at the intersection of old traditions and modern technologies, have made it possible to achieve excellent results of their use for a variety of purposes.

Esbe products are quite popular today. is no exception. It is one of the many elements that make up the life support system for residential buildings.

The need to use

This design, on the one hand, is quite simple, but on the other hand, it is designed to perform an extremely important task, being part of engineering networks. Everyone knows the rule that demand creates supply, which is why you can find many models on the market today, which are represented by all kinds of manufacturers. However, valves manufactured by Esbe are distinguished by excellent performance. A three-way valve of this type can be purchased at an affordable cost. This is confirmed by user reviews.

Design features

Today you can find Esbe products in a wide range. The three-way valve is no exception. This element has a regulating component, which is a ball or stem. The latter moves vertically, but as for the ball, its movement occurs around its axis. Due to the fact that the movements of the regulating element do not allow shutting off the flow of liquid, distribution and mixing occurs. The most common and simple models are cranes.

The main plus

Their main advantages are low cost and simplicity. However, if you need to adjust the Esbe three-way valve, then you should exclude the purchase of simple devices, since they have the main disadvantage, expressed in the inability to stabilize the temperature at the outlet.

Installation work

Almost all the described valves on the market are connected on the basis of one circuit. Most often, mixer taps are used in water supply systems. Their main goal is to reduce the risk of backflow. There will inevitably be a pressure drop between the cold and hot water streams. It can cause reverse flow. If you install the valve, then you will not face such a problem. If we are talking about a heating system, then such devices are used exclusively in three directions, namely to stabilize the temperature regime of the coolant flow in the incoming pipeline of boiler equipment, to reduce the supply of high-temperature water from the heating device to the pipeline, as well as in the conditions of mixing units of systems by the type of warm floor.

Mixer connection

If you are interested in Esbe products, the three-way valve can be purchased at any store of relevant goods. One has only to consider before this, how the tap is used in the underfloor heating system. The use of a mixing unit allows you to create an additional circuit in the system. It connects with two points to ensure constant circulation of the outlet water. With regard to the inlet, the flow is provided only if there is a need for additional heat. A valve with a thermostat is connected to the mixing unit. Due to the fact that all valves are located at the point, they are narrowed, which can cause insufficient flow of pumping equipment. To increase it, it is necessary to create an additional line, with the help of which it is possible to reduce the consumption of electricity by the pump. During the installation process, it is worth remembering that the second line is not always required. A number of valve models have a sufficiently large bore. The Esbe three-way valve, the connection diagram of which can be developed based on the instructions presented in the article, may assume insufficient flow in the first line. In this case, the thermostat is not able to open the passage of the required size. This issue can be easily solved in two ways: the first assumes a narrowing of the second line, while the other option is to mount it on it. The last option is considered more productive, since it allows you to adjust the flow.

Alternative installation work

The Esbe three-way valve can be installed using a different method. It does not involve the use of a balancing valve. The pump is connected to the second line, eventually the temperature of the outlet and inlet flows is equalized. The thermostat valve is in single circuit systems. The simplest example of such systems is underfloor heating in small rooms. In this case, it is not always justified to create a mixing unit with large dimensions. It would be best to connect the underfloor heating system using one circuit. If you are thinking about how to connect an Esbe three-way valve with an electric drive, then it can be located on the return line along which cooled water runs. In this case, the thermostat will cause the shut-off valves to move, the cross-section will be increased, and the flow will be open. As soon as the pipe is heated, the temperature sensor will detect this and reduce the flow.

Installation of a valve for a heating boiler

This issue, 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 the heating equipment. If this requirement is not taken into account, then condensation will appear on the pipes, temperature drops will lead to deformation at the points of the joints. If we talk about the consequences of deformation, then at best you will encounter a small leak, while at worst the system will need to be completely changed. In order not to need to repair the Esbe three-way valve, it is important to connect shut-off valves to the boiler, which is characterized by temperature differences during operation. If you install a mixing valve, then you can ensure that water does not enter the equipment inlet, the temperature of which is below 50 degrees. The temperature drop is significantly reduced, the negative impact of cold is reduced. Experts advise adding mixing valves to systems that are equipped with plastic pipelines. In this case, the task is to exclude the ingress of water with a high temperature into the pipeline. While polymers have many benefits, they are quite poor at coping with frequent temperature extremes that can be higher than operating temperatures.

When exposed to such conditions, the pipeline system fails soon enough. Experts advise choosing Esbe products. The three-way valve, the installation instructions for which are presented in the article, has been manufactured by this company for a long time. If you use this element, then you will be able to provide temperature readings in the range from 75 to 85 degrees, which are recommended by specialists. The installation of the valve allows you to cope with many problems, however, the model must be selected in accordance with the characteristics of the network, and also have a sufficiently large passage.

Adjustment features

When purchasing the Esbe products - a three-way valve, the installation and adjustment instructions for which are presented in the article - you should remember that with the help of this device it is possible to mix the cooled water from the return line into the supply. For high-quality regulation, not only a three-way valve, but also a four-way valve, which must be present in the heating system, is independently installed in the system. It is placed directly in front of the underfloor heating contour. The handle allows you to open the bypass, while the circulation pumps and equipment draw in 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, you need to figure out what happens at certain positions of the handle. The latter can be set to the bypass overlap position, while the hot coolant will flow into the pipe of the underfloor heating system. As for the mode in which the supply is shut off, the water enters the tank and runs in a small circle. The third position allows feeding the flow from the return system without blocking the full cycle of water flow along the entire circuit.

Conclusion

Recently, experts increasingly recommend purchasing Esbe brand products. The three-way valve, the instructions, the wiring diagram of which are presented in the article, is just an example of this. 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 install, observing the technology.

A three-way valve in a water supply or heating system is responsible for mixing or separating liquids of different temperatures, as well as for obtaining the required temperature at the outlet of the liquid (adjusting the temperature of the coolant using a servo drive).

Design features

The body of the device contains two inlet and one outlet for the flow of liquids and a regulating element, which can be of different design (for example, a rotary ball or a travel rod), also a place for a servo drive.

Typically, the valve is not designed to completely shut off the liquid outlet flow, but is only able to control the mixing ratio of the liquids and the temperature in the system. The instruction does not imply, but functionally, it is quite possible to shut off the fluid supply.

A three-way valve of a certain type, which performs a separating function, can have a rotary servo drive to redirect the flow to different pipes (then it is called "shut-off").

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

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

Hydraulic slewing drive;
Pneumatic drive;
Electric servo.

So, threeho The new Esbe valve, having a servo drive, will assume the actual sample itself and a compatible drive from the same company.

Types and differences

Esbe has been in business for over a century and specializes in temperature control products for hydraulic systems in small buildings.

It manufactures a valve and rotary actuator for cooling or heating systems, which also work in conjunction with indoor and outdoor temperature sensors in the system. The principle of operation of the Esbe three-way valve is similar to the above options.

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

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

Rotary valves

Valves series VRG130 are used for hot / cold water supply systems. This model range, like the subsequent ones, has various options (for example, the three-way valve from Esbe VRG 131 also belongs to this series and has a connection for a servo drive).

They are compact brass alloy mixers designed to minimize leakage and with a manual dial. The manual indicates that they are also compatible with automatic control systems and Esbe controllers, which allow automating the operation of valves.

The Esbe three-way valve of this model series - comes with standard sizes DN 15-50, pressure class - PN 10, model options provide versions with an internal (three-way mixing valve of the Esbe type, model VRG131 with a connection for a drive), external thread

(model VRG132), with union nut or compression fittings.

Three-way The Esbe VRG330 series mixing valve has similar qualities to the previously described VRG131 series (DN 20-50, PN 10), but it is specially designed to work with large flows (kvs difference between inlets 60 percent).

It can also be equipped with compatible controllers and automatic controls. Available with three types of connections: internal thread, external thread, rotating nut.

According to Esbe specification, 3F series rotary mixing valves are designed for heating and cooling applications.

Esbe controllers and automatic control systems can also be used with them (the Esbe three-way crane model VRG131 with an electric drive is not immediately supplied, which allows you to choose the most convenient option for the company's products).

For ease of installation, the Esbe 3F three-way valve is marked with an adjustment scale on both sides. The valve body is made of cast iron, also the model is supplied with an adapter for flanged pipe PN 6, model sizes - DN25-150.

The mixing valve from Esbe series H (DN25-40) and HG (DN25) is designed for installation in confined spaces.

This Esbe 3-way control valve is used only for heating systems and is specified for boiler group operation (made of cast iron, special "H" -shaped body). It also has a reasonable price tag.

As the main type of connection, both an internal thread and its mixed type are used. Compatible with Esbe controllers and actuators like VRG131.

Models of the VRH130 series are also made in "H" -shaped version, but made of brass with pressure class PN 10. This model is more versatile than the previous model and can also be used in water supply systems, it is produced with different body widths.

Linear valves

The VLF300 series is a three-way in-line mixing valve with sizes DN 15-50.

This model range is made Flax made of nodular cast iron and can be used with a working fluid, both cold / hot water, and which contains non-freezing components (glycol, for example).

In the latter case, the sample must be equipped with a stem heater. It is completed with a flange for PN 6 pipe. Models similar to those indicated earlier, VLF200 dn25 - have a high working pressure up to 16 bar (versus 6 bar for the previously indicated model range).

Models VLE132 - made of bronze with standard sizes DN 15-50. These are linear motorized valves, which, like the previously indicated similar models, can use water with glycol as working fluids (connection - external thread PN16), in contrast to the VRG131 series. Its price ranges from 140 to 350 euros.

All specified linear 3-way valves are compatible with Esbe controller and actuator.

Thermostatic mixing valve

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

A feature of this model range is that the Esbe three-way thermostatic valve is supplied with specialized protection against burns, since the liquid circulating in the system is of a sufficiently high temperature.

Esbe's three-way thermostatic mixing valve with "scald protection" features a sensor that automatically shuts off the servo for hot water supply if cold water is not supplied.

The coolant with which these models work is water (including drinking water), the coolant of closed systems is water with non-freezing components. The pressure class is PN 10, the body is made of corrosive resistant brass, for example the VRG131 valve is not suitable for such a system.

VTA330 / 530 - a thermostatic mixing valve from Esbe of this series is designed to work in domestic hot water systems, as well as in taps or showers when no other temperature control is provided (VTA330), or in domestic hot water systems with a high flow (VTA530). Its price is around 150 euros.

Also equipped with a protection system you are from burns. Pressure class PN 10 (corrosive resistant brass material), available with male threaded connections, fittings or adapters.

VTA360 / 560 - a series similar to the previous one, but equipped with a large number of fittings and connections. The manual assumes that the actuator of the Esbe three-way device of this series must also be compatible with the specifications indicated by the company.

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

These valves are recommended for use in hot water circulation systems (HWC) or for underfloor heating systems. Also equipped with "scald protection". VTA370 / 570 - models designed for use in the "warm floor" system have a high flow capacity.

VTA310 is a sample supplied with an adjustment knob, without a scald protection system. It is used in domestic water supply systems, including a closed loop hot water supply system (HWC). The price starts from 50 euros.

Features of installation and prices

When installing a three-way mixing valve, various options, instructions and algorithms are selected according to which the installation is carried out. As a rule, the part is not installed directly to the heat source, as the system uses a pressureless manifold or "hydraulic arrow".

In the version for heating, the simplified instruction assumes the supply of heat carrier from the boiler to the valve, from there the heat carrier is supplied to the heating system through a pump.

The liquid that passed through the heating system and cooled down is sent to the boiler for heating, but also to the mixing valve, which ensures the temperature control of the supplied substance.

The instruction for the Esbe three-way valve usually involves a description of how to connect the valve to the system, which, depending on the model range, may be different.

A three-way valve cw602n Esbe (brass grade is indicated here) of the VRG130 model range (namely, VRG131 ½) costs an average of $ 170 (if purchased with an actuator).

The price of a three-way valve from Esbe linear VLA330, depending on the configuration, is $ 150 (not equipped with an electric actuator).

The Esbe three-way thermostatic valve (VTA 320) can be priced at $ 70 or more.
