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.

Solenoid safety gas valves block unit in angle version is a set of solenoid safety gas valves and other gas fittings unit assembled into a single gas train (gas filter, pressure regulator-stabilizer, motorized gas valve, safety relief gas valve, safety shut-off gas valve, pressure switch, etc.).
In the units, the main safety valves and the gas filter are applied in an angle version.
Valve block units in angle version can be used at facilities where the circumstances are such that it would be difficult to assemble a linear block unit due to the face-to-face length. Furthermore, such units can be used in the process of design and development of measures aimed at restructuring of heat and power facilities, where the replacement of outdated gas train is required and the space is limited due to the existing gas pipeline supply, location of the boiler units and gas igniters.
TERMOBREST’s gas valve block units are suitable for any automated control system of boiler and burner equipment and can be used in the gas supply circuits for steam and hot water boilers of various types, including high-power boilers: PTVM, DKVR, DE and KVGM.
ADVANTAGES:
- Shorter face-to-face length of a gas train;
- Hydraulic resistance factor is 40% less compared with linear valve block units;
- A variety of standard models, with the possibility of developing individual solutions for specific projects;
- The use of TERMOBREST’s angle valve block units allow to significantly reduce the dimensions and consumption of gas pipeline valves of the burner, the number of welded joints, working hours for assembling and commissioning works, and to increase the operating reliability and length of service.
TECHNICAL SPECIFICATIONS for gas valve block units in angle version:
- DN 40…200, flanged connection;
- Рmax – 6 bar (0,6 МPа).
CLIMATIC VERSION:
- (-30…+60 °С);
- (-45…+60 °С);
