Parker Quick Couplings
Hydraulic Accessories, Pressure Relief Valve
Pressure Relief Valve for medium pressure applications up to 250 bar. Available made of brass/steel.
Parker's Pressure Relief Valve is produced for hydraulic systems where in line quick connect couplings are used. The system pressure built up between the hydraulic unit and the coupling would not allow mechanical coupling. The Pressure Relief Valve can be mounted directly in the main inflow line so that all downstream pipe or hose lines where quick connect couplings or plugs are installed at the ends can be depressurised.
