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).

Solenoid safety gas valves block unit in angle version is a set of solenoid safety gas valves and other gas fittings unit assembled into a single gas train (gas filter, pressure regulator-stabilizer, motorized gas valve, safety relief gas valve, safety shut-off gas valve, pressure switch, etc.).
In the units, the main safety valves and the gas filter are applied in an angle version.
Valve block units in angle version can be used at facilities where the circumstances are such that it would be difficult to assemble a linear block unit due to the face-to-face length. Furthermore, such units can be used in the process of design and development of measures aimed at restructuring of heat and power facilities, where the replacement of outdated gas train is required and the space is limited due to the existing gas pipeline supply, location of the boiler units and gas igniters.
TERMOBREST’s gas valve block units are suitable for any automated control system of boiler and burner equipment and can be used in the gas supply circuits for steam and hot water boilers of various types, including high-power boilers: PTVM, DKVR, DE and KVGM.
ADVANTAGES:
- Shorter face-to-face length of a gas train;
- Hydraulic resistance factor is 40% less compared with linear valve block units;
- A variety of standard models, with the possibility of developing individual solutions for specific projects;
- The use of TERMOBREST’s angle valve block units allow to significantly reduce the dimensions and consumption of gas pipeline valves of the burner, the number of welded joints, working hours for assembling and commissioning works, and to increase the operating reliability and length of service.
TECHNICAL SPECIFICATIONS for gas valve block units in angle version:
- DN 40…200, flanged connection;
- Рmax – 6 bar (0,6 МPа).
CLIMATIC VERSION:
- (-30…+60 °С);
- (-45…+60 °С);
- (-60…+60 °С);
- (-60…+60 °С);
AMBIENT TEMPERATURE:
- -60…+70°С;
- -45…+120 ˚С (special version);
- -45…+90 °С (special version – is indicated in structure).
POWER SOURCE, V:
