Safety relief valves PSK

Safety relief valves PSKSafety relief valves PSK are the diaphragm type devices that designed for gas discharge when pressure increases above the tolerance limit.

Valve PSK is installed at the pipelines, gas distribution station of low, medium and high pressure.

The valve is provided with a device for force purging.

Ambient class "UZ" (GOST 15150, from -40 to +45° C). Nominal inside diameter is DN 25 and DN 50.
