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.

SOLENOID SAFETY GAS VALVES BLOCK UNIT
Solenoid safety gas valves block unit is a set of solenoid safety gas valves and other gas fittings unit assembled into a single gas train (gas filter, pressure regulator-stabilizer, safety relief gas valve, safety shut-off gas valve, pressure switch, etc.) and motorized gas valve
Motorized gas valve included in the unit controls the gas supply to the gas burner and regulates the gas flow rate.
Upon customer's request, the valve block can be manufactured complete with additional automation devices (pressure switches, position indicators of valves), as well as in general industrial and waterproof versions.
The gas block can be designed according to the scheme, which provides the possibility to check the tightness of the valves included in the block before ignition of the burner.
FLOW CONTROL RANGE:
- 0.05 to 100 % of nominal.
TYPE OF REGULATION:
- proportional;
- position control;
- manual regulation.
DIAMETER NOMINAL:
- DN 15÷300.
HOUSING MATERIAL:
- steel: DN 15÷300;
- iron cast: DN-150, DN-200;
- aluminum: DN 15÷200.
CLIMATIC VERSION:
- -30…+60 °С – installation in irregularly heated rooms;
- -45…+60 °С – installation under roof;
- -60…+60 °С – installation under roof;
- -60…+60 °С – outdoor installation.
AMBIENT OPERATING TEMPERATURE:
All solenoid safety gas valves block units manufactured by TERMOBREST are supplied in a version with ambient operating temperature from -60 up to +70 ° C.
Upon customer’s individual request, solenoid safety gas valves block units can be manufactured with ambient operating temperature from -45 up to +120 ° C.
Upon customer’s individual request, the valves block units with the read-off position indicators can be manufactured with ambient operating temperature from -45 up to +90 ° C (the upper range is limited by the permissible operating limit (range) of the read-off position indicator).
