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).

PRESSURE SWITCHES
Pressure switches are used as excess-pressure and under-pressure differential monitoring devices for natural gas, liquified gas and air in gas supplying and ventilation systems.
Pressure switches monitor extremely slight pressure differences and provide for electrical disconnection of a system when the set value is reached.
