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.
