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 RELIEF VALVES
Safety relief valve is a device designed for output pressure depression by means of releasing gases into the atmosphere or into a low pressure system when the set limit of the controlled pressure is above the requested value. Safety relief valve ensures protection of gas equipment from damage and prevents emergencies.
FIELD OF APPLICATION:
Safety relief valve is installed usually on the relief line next to the pressure regulator and applied at gas distributing plants/units and other equivalent equipment and installations, which require maintenance of the constant value of gas flow rate pressure.
MAXIMUM OPERATING PRESSURE:
- up to 6 bar.
DIAMETER NOMINAL AND HOUSING VERSION:
Coupling DN 15÷50
Flange DN 15÷50
HOUSING MATERIAL:
- aluminum;
- steel.
VERSION:
Safety relief valve can be equipped with the device of forced opening operation, by means of which valve can be opened in manual mode.
CLIMATIC VERSION:
- -30…+60 °С;
- -40…+60 °С.
OPREATING MEDIUM TEMPERATURE:
- from -30 to +70 °С.
