Three-position solenoid safety gas valves
Three-position solenoid safety gas valve is a device designed for remote control of flow of non-aggressive gaseous mediums in three different modes:
- maximum flow rate mode;
- average (intermediate) flow rate mode;
- off mode.
Three-position solenoid safety gas valves are applied at automated systems of gradual gas flow control.
Such valves combine shut-off (cut-off) unit with manual gas flow regulator and unit of average (intermediate) gas flow in one housing. This design ensures gradual gas flow control as well as manual adjustment of average gas flow rate from 10 to 60 %.
Customized valves can be manufactured with two flow regulators that allow to adjust gas flow rate from 10 to 100 %.
OPERATING PRESSURE:
- from 0 to 3 bar (up to 0,3 mPa).
DIAMETER NOMINAL:
- DN 20÷50.
HOUSING MATERIAL:
ALUMINUM
STEEL
Valves in aluminum housings are applied at thermal power facilities (boiler houses, furnace rooms etc.), and also by manufacturers of gas equipment (modular boiler houses, boilers, burners, furnaces, flare facility etc). Low weight, cost and small dimensions make valves in aluminum housings practical in application.
Valves in steel housing are applied primarily at large power plants (heat and thermal power plants, condensation power plants etc). Steel housings are highly resistant to static and dynamic loads due to requirements of equipment application at large power plants.
CLIMATIC VERSION:
- -30…+60 °С – installation in irregularly heated space;
- -45…+60 °С – installation under cover;
- -60…+60 °С – installation under cover;
- -60…+60 °С – outdoor installation (only for explosion proof version);
OPERATING ENVIRONMENT TEMPERATURE:
- -60…+70 °С (standard version);
- -45…+120 °С (customized version).
ADDITIONAL FUNCTIONS AND DEVICES:
- all gas valves can be equipped with external read-off position indicators (opened/closed);
- for additional devices such as manometers, pressure switches, pulse tubes etc. connection valves are equipped with plugged threaded connections G1/4”.
HOUSING VERSIONS:
- flange;
- coupling.
EXPLOSION PROOF VERSION:
- general purpose industrial version;
- explosion proof version.
General purpose industrial version of valves is applied at all gas facilities, where there are no special requirements for ensuring explosion safety of electrical equipment.
Explosion proof version of valves is applied at the facilities and premises with special protective measures requirements upon designing, manufacturing and operating of electrical plants.

GAS PRESSURE REGULATORS-STABILIZERS
Pressure regulators-stabilizer is a device designed for reduction, regulation and maintenance of the pressure (flow) of hydro carbonated gases, gaseous phases of liquefied gases, compressed air as well as other non-aggressive gases constant at the outlet within prescribed limits regardless of inlet pressure. Pressure regulators-stabilizers can operate without external power source.
FIELD OF APPLICATION:
Gas distributing plants, heating plants, gas reciprocating engine power plants, gas burners and other equivalent equipment and installations, which require reduction and maintenance of the constant value of gas flow rate pressure.
MAXIMUM OPERATING PRESSURE:
- up to 6 bar
DIAMETER NOMINAL:
DN 15÷150
HOUSING MATERIAL:
- aluminum;
- steel.
VERSIONS:
1. Standard version (DN 15÷150) - designed for reduction, regulation and maintenance of the gas pressure within prescribed limits.
2. Regulator with in-built safety relief valve (DN 15÷150) – designed for reduction, regulation and maintenance of the gas pressure within prescribed limits and has function of gas discharge to the atmosphere (gas path) in case if controlled pressure is exceeded.
3. Combined regulator both with safety shut-off (DN25÷100) – designed for regulation and maintenance of the gas pressure within prescribed limits, and also stops gas supply, when prescribed gas outlet pressure is exceeded.
4. Combined regulator, both with safety shut-off valve and safety relief valve – designed for regulation and maintenance of the gas pressure within prescribed limits; has function of gas discharge to the atmosphere (gas path) when controlled pressure is exceeded, and also stops gas supply, when prescribed gas outlet pressure is exceeded;
Combined regulators-stabilizers can be manufactured in following versions:
- with safety shut-off valve and safety relief valve in separate housings.
- with safety shut-off valve and in-built safety relief valve.
- with safety shut-off valve and safety relief valve in one housing (monoblock unit version).
- combined household regulator, both with safety shut-off valve and safety relief valve. Such regulators are applied at the gas supply systems of residential and small-apartment houses as a part of household gas distributing plants.
5. Zero pressure regulator (DN 15÷150) - designed for proportional regulation of gas flow rate depending on rarefaction at the outlet or at the control point of pipeline, and maintenance of gas-air mixture in a constant ratio.
6. Gas-air pressure ratio regulator (DN 15÷150) - designed to obtain a gas-air mixture in the required ratio and automatically maintain this ratio.
CLIMATIC VERSIONS:
- -30…+60 °С
- -40…+60 °С
OPERATING MEDIUM TEMPERATURE:
- from -30 to +70 °С.
