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).

SAFETY SHUT-OFF GAS VALVES
Safety shut-off gas valve is a device designed for automatic cutoff of the gas supply in case of pressure boost above requested actuation value.
FIELD OF APPLICATION and OPERATING PRINCIPLE:
Safety shut-off valve is usually installed in gas distributing plants and units in front of the pressure regulator-stabilizer and provides control of the output pressure received behind the regulator. The signal about the deviation of the gas pressure from the set value is sent to the safety shut-off valve through the impulse tube connected to the output pressure gas pipeline. The value of the monitored pressure is adjusted by regulating the spring in the safety shut-off valve. When the set value of pressure behind the regulator is exceeded, the safety shut-off valve closes and shuts off the gas supply in the pipeline. The valve can only be opened manually after eliminating the cause of gas pressure excess above the controlled one.
MAXIMUM INPUT PRESSURE:
- up to 6 bar.
ADJUSTMENT RANGE OF CONTROLLED PRESSURE:
- 60-230 mbar;
- 200-440 mbar;
- 420-700 mbar.
Upon individual request: manufacture with different adjustment range.
