How the EVGNC valve works

In the absence of voltage, the EVGNС valve is closed, and in the presence of voltage and the stem is cocked, it opens. When the EVGNC valve is operated, for example, with a gas detector, after a gas leak occurs, the alarm relay contacts close, the valve is energized, and the valve shuts off the gas supply. Closing time less than 1 sec. To open the valve, cock it using the cocking rod.

PRICE for EVGNC valves

Solenoid gas valve is one of the devices pipe fittings, intended for distribution and regulation of the working environment in gas supply systems, as well as on gas pipelines. Home distinctive feature The solenoid gas valve is a remote control, which is carried out by means of electricity supply. An electrical impulse initiates the movement of an electromagnet in a given direction, which in turn sets the movement of the shutter.

Solenoid gas valve device

The working element of a gas solenoid valve is a seat - an opening located inside the body for the passage of the working medium, as well as a shutter. Depending on the model and configuration of the device, the shutter can be made both in the form of a plate and in the form of a piston. Making reciprocating movements, the shutter opens or shuts off the gas supply. It is mounted on a magnetic rod (core), which is connected to an electromagnet. The electromagnet coil itself is installed in the upper part of the body on the outside of the valve.

Gas solenoid valve: principle of operation

The principle of operation of the electromagnetic gas valve is that when electricity is applied to the coil, a magnetic field is created. Under the influence of this field, the electromagnet is drawn into the coil, and thereby sets the direction of movement of the shutter.

During operation, the valve is subjected to two forces - on the one hand it is the force of resistance to the return spring, and on the other hand it is the force of the magnetic field. The latter is regulated by the strength of the electric current - the stronger electricity, the greater the force with which the force of the spring is overcome. Thus, by adjusting the current supply, it is possible to regulate the degree of opening or closing of the electromagnetic gas valve, and, consequently, the supply of the working medium.

When the power is turned off, the valve returns to its original position, which is determined by its design.

Varieties of electromagnetic gas valves

All models of gas solenoid valves that exist today can be divided into three large groups:

Normally open (NO). When the power supply is cut off, the normal open gas valves are in the open position, providing free passage of the working medium.

• Normally closed (NC). Normally closed solenoid valves without power supply come into a closed state, thereby shutting off the flow of gas in a pipeline or any system.
• Universal. Universal gas solenoid valve designed in such a way that it can remain open or closed in the event of a power outage.

As for other differences, here we can highlight solenoid gas valves direct and indirect action. The former assume that the valve plug is actuated only by the movement of the core; the latter use not only the core to move the shutter, but also the force of the working medium, which can significantly save effort during large passages.

Solenoid gas valves also differ in the number of strokes. Currently there are:

Two-way valves with only inlet and outlet. Devices of this type are intended solely for supplying or blocking the working medium into any system.

• Three-way valves with one inlet and two outlets. Such an electromagnetic gas valve can not only pass, but also redirect the gas flow in the system.
• Four-way valves are devices that have four holes - one inlet and three outlets. Like three-way valves, they can redistribute the flow of the working environment, but unlike them, they provide more opportunities for connecting to various systems.

It should be noted that inside each type of electromagnetic gas valves there are many models and modifications of these devices, differing both in size and functionality. For example, according to the operating conditions, some valve models may have special coating resistant to aggressive media.

Where to buy a solenoid gas valve?

Solenoid gas valves are devices that operate on gas pipelines, and their failure can lead to the most backfire. That is why valves must meet the most stringent requirements for their safety and reliability. And this means that you need to purchase them only from a well-established manufacturer.

JSC "Penza Valve Plant" is an enterprise with more than half a century of history. During the operation of the plant, our devices have repeatedly proved their highest quality and unsurpassed reliability. Therefore, if it is necessary to purchase pipeline fittings, we recommend that you pay attention to the products of PAZ OJSC, among which there are various models electromagnetic gas valves.

The solenoid valve for water, gas, oil products, which has a shut-off and control design, is actively used in modern industry. The valve allows you to remotely control heating and thermal equipment, as well as gas flows in pipelines. With the use of a gas solenoid valve, the general security systems, with low power consumption, the equipment is highly reliable and long term service with sufficient purity of the fuel (no inclusions of mechanical impurities).

Main types of solenoid valves

Versions EVGNA

How the EVGNA Valve Works

When not energized, the EVGNA valve is open, and when energized and the stem is cocked, it closes. When the EVGNA valve is operated, for example, with a gas detector, after a gas leak occurs, the alarm relay contacts open, the valve is de-energized and shuts off the gas supply. Closing time less than 1 sec. To open the valve, it is necessary to apply voltage to it, then cock it by pressing the cocking rod.
