RQM*-W
The RQM*-W are pilot operated pressure relief valves with BSP threaded ports, available in two nominal sizes for aflow rate up to 400 l/min.


RQM*-P
Pilot operated pressure relief valve; main stage with shutter and cone seal.


MRQA
MRQA is a pressure relief and safety valve with automatic unloading. Upon reaching the set value, the valve freely unloads the pump and puts it under pressure again when the pressure values descend in the circuit to correspond to 68%or 78% of the set value.


RQ*M*-P
TThe RQRM and RQAM valves have not only the normal functionof relief valves or safety valves but also the characteristic of freely discharging the pump flow either when the set pressure value is reached or when the solenoid valve is de-energized.


RQ**-P
The RQR and RQA valves have not only the normal function of relief valves or safety valves but also the characteristic of freely discharging the pump flow when the set pressure value is reached.



RQM*K*-P
The RQM*K-P valves are explosion-proof pressure relief, available in in ISO 6264 (CETOP RP 121H) subplate version with three nominal sizes for flow up to 500
l/min.
