Safety Shut-off Valve for Pressure Protection in Gas and Air Systems (ПЗК)

The safety shut-off valve (SHC) is designed to protect against emergency pressure changes in vessels and various pipelines for natural gas, propane-butane, nitrogen, air and other non-aggressive gases by automatically shutting off the flow of the medium when the set pressure is reached, as well as to protect the heating system from gas breakthrough in case of failure of heating equipment (heat exchangers) by automatically shutting off the flow of the coolant.
Safety valves are used at gas regulator stations, in gas regulator units and at other gas supply facilities.
