SOLENOID SAFETY GAS VALVES
Solenoid safety gas valve (the valve) is a device designed for usage in systems where remote control of the flow of non-aggressive gaseous medium and liquids is required.
OPERATING PRESSURE:
Operating pressure range of the valve (ВН and BF type):
- 0 to 6 bar (mPa);
- Operating pressure is a maximum overpressure at which adjusted operating mode is maintained.
NOMINAL DIAMETER:
Nominal diameter range of TERMOBREST valves: 15 to 300 mm. Such wide range of nominal diameter types allows covering all demands of the market of gas equipment of low, medium and high pressure.
INITIAL STATE:
- normally closed (closed in de-energized state);
- normally opened (open in de-energized state).
HOUSING MATERIAL:
- steel: DN15÷300;
- cast iron: DN-150, DN-200;
- aluminum: DN15÷200.
Valves in aluminum and cast iron housings are applied at thermal power facilities (boiler houses, furnace rooms etc.), technical gas lines of different plants and factories (chemical, petrochemical, extractive, food, building materials 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 VERSIONS:
- -30…+60 °С – operation in irregularly heated space;
- -45…+60 °С – operation under cover;
- -60…+60 °С – operation under cover;
- -60…+60 °С – outdoor operation (only for explosion proof version).
OPERATING ENVIRONMENT TEMPERATURE:
By default, all gas valves manufactured by TERMOBREST are supplied in a version designed for working environment with temperature range from -60 to +70 ° C. By special order the valves can be manufactured for working environment with temperature range from -45 до +120 °С.
BY ITS FUNCTIONALITY AUTOMATIC SOLENOID VALVE CAN BE OF TWO TYPES SHUT-OFF VALVE AND SHUT-OFF CONTROL VALVE:
Shut-off valve
Shut-off control valve
- Shut-off valve ensures fast opening/closing (operation time 1 second max) and is applied in systems, where it is necessary to stop medium flow in emergency situation or by technological requirements. Also such valve is applied to control medium supply in gas facilities.
- Shut-off control valve ensures fast opening/closing as well as adjustment of the medium pass in open state of the valve. Shut-off control valve is applied to control medium flow, ensuring necessary operating modes of gas facilities and devices. Control of medium adjustment can be both in manual and automatic modes.
ADDITIONAL FUNCTIONS AND DEVICES:
Valves of BH and BF type can be equipped with valve’s trim position indicator, which transmits information to the control board or automation about the current state of the trim (open or closed).
Besides that valves can be manufactured with manual start-up function of electric or mechanical type. Manual start-up function ensures guaranteed protection of the device from its inadvertent opening in emergency situation.
HOUSING TYPE:
Linear (standard)
Angle
Standard (linear version) valves are applied on the straight pipeline sections.
Angle valves are applied at the facilities with limited space (corner sections of the pipeline etc.) and allow reducing number of welding joints and connections during installation.
Flange (DN15÷300) connection
Coupling (DN15÷50) connection
Valves with flange connection are manufactured with flanges PN 6 (by default) or PN 16 (on request).
Valves with nominal diameter 15÷50 mm can be manufactured in monoblock unit version, i.e. two and more devices are unified in one housing. Such design ensures maximum functionality with minimal product dimensions.
VERSIONS:
General purpose industrial version
Explosion proof version
General purpose industrial versions of valves are applied at all gas facilities, where there are no special requirements for ensuring explosion safety of electrical equipment.
Explosion proof versions of valves are applied at the facilities and premises with special protective measures requirements upon designing, manufacturing and operating of electrical plants.
Explosion proof electrical equipment is a special type of electrical equipment that is designed to eliminate ignition of the explosive environment surrounding it during the operation of this electrical equipment.

SOLENOID SAFETY GAS VALVES (double action)
Solenoid safety gas valve (double action) is a device designed for control and regulation of gaseous mediums supply in gas burners of hot water and steam boilers, melting and drying furnaces, gas heaters and other gas consuming devices where the multi-step control of the flow is required.
Double action solenoid safety gas valves are composed of two shut-off safety gas valves and additional devices functioning in one housing, which allows combining various functions in one product:
- two shut-off safety gas valves
- shut-off safety gas valve – three-position solenoid safety gas valve (high/low gas flow mode)
- two shut-off safety gas valves and smooth opening function
- two shut-off safety gas valves and gas flow regulator (electromechanical or manual)
- multiblock unit based on the double valve.
ADVANTAGES (as compared with valve block units, assembled with single items):
- smaller overall dimensions (up to 30%);
- low total factor of hydraulic resistance;
- reduced time spent on installation and maintenance.
DIAMETER NOMINAL:
- 15; 20; 25; 32; 40; 50.
OPERATING PRESSURE:
- from 0 up to 6 bar (up to 0,6 Mpa).
CONNECTION TYPE:
- flange;
- coupling.
CLIMATIC VERSIONS:
- -30…+60 °С;
- -45…+60 °С;
- -60…+60 °С.
AMBIENT TEMPERATURE:
- -60…+70 °С (standard);
- -45…+120 °С (upon individual request).
ADDITIONAL FUNCTIONS AND DEVICES:
- can be equipped with position indicators of the shutter, pressure switches, manual or electromechanical flow regulator, density (leak- tightness) control valve;
- for connection of pressure switches, manometers, impulse tubes or other devices and instruments, the holes with G1/4” thread closed with plugs, are provided in the housing.
EXPLOSION PROOF VERSIONS:
- general industrial usage (protection degree IP65);
- explosion proof (protection degree IP67).
