The RQM*-P valves are pressure relief valves available in three nominal sizes for flow up to 500 l/min. — They are available in ISO 6264 (CETOP RP 121H) subplate mounting version. — Available in five versions that allow, by means of a solenoid valve, unloading of the total flow and selection up to three pressure values (see table 2

Pilot oil supply and pilot oil return (see also Symbols on page 4) The pressure relief valve can be unloaded or switched to.

The symbol shows that the spring cavity has a drain to the tank. Application of pressure-reducing valve. Let us consider a hydraulic circuit 

Unloading valves are used to unload the pump to tank when the pressure in a separate part of the circuit reaches a pre-set level.
