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).

GAS PRESSURE REGULATORS-STABILIZERS
Pressure regulators-stabilizer is a device designed for reduction, regulation and maintenance of the pressure (flow) of hydro carbonated gases, gaseous phases of liquefied gases, compressed air as well as other non-aggressive gases constant at the outlet within prescribed limits regardless of inlet pressure. Pressure regulators-stabilizers can operate without external power source.
FIELD OF APPLICATION:
Gas distributing plants, heating plants, gas reciprocating engine power plants, gas burners and other equivalent equipment and installations, which require reduction and maintenance of the constant value of gas flow rate pressure.
MAXIMUM OPERATING PRESSURE:
- up to 6 bar
DIAMETER NOMINAL:
DN 15÷150
HOUSING MATERIAL:
- aluminum;
- steel.
VERSIONS:
1. Standard version (DN 15÷150) - designed for reduction, regulation and maintenance of the gas pressure within prescribed limits.
2. Regulator with in-built safety relief valve (DN 15÷150) – designed for reduction, regulation and maintenance of the gas pressure within prescribed limits and has function of gas discharge to the atmosphere (gas path) in case if controlled pressure is exceeded.
3. Combined regulator both with safety shut-off (DN25÷100) – designed for regulation and maintenance of the gas pressure within prescribed limits, and also stops gas supply, when prescribed gas outlet pressure is exceeded.
4. Combined regulator, both with safety shut-off valve and safety relief valve – designed for regulation and maintenance of the gas pressure within prescribed limits; has function of gas discharge to the atmosphere (gas path) when controlled pressure is exceeded, and also stops gas supply, when prescribed gas outlet pressure is exceeded;
Combined regulators-stabilizers can be manufactured in following versions:
- with safety shut-off valve and safety relief valve in separate housings.
- with safety shut-off valve and in-built safety relief valve.
- with safety shut-off valve and safety relief valve in one housing (monoblock unit version).
- combined household regulator, both with safety shut-off valve and safety relief valve. Such regulators are applied at the gas supply systems of residential and small-apartment houses as a part of household gas distributing plants.
5. Zero pressure regulator (DN 15÷150) - designed for proportional regulation of gas flow rate depending on rarefaction at the outlet or at the control point of pipeline, and maintenance of gas-air mixture in a constant ratio.
6. Gas-air pressure ratio regulator (DN 15÷150) - designed to obtain a gas-air mixture in the required ratio and automatically maintain this ratio.
CLIMATIC VERSIONS:
- -30…+60 °С
- -40…+60 °С
OPERATING MEDIUM TEMPERATURE:
- from -30 to +70 °С.
