Pilot Operated Proportional Pressure Relief Valve - Series R4V/R6V OBE

*PRODUCT IMAGE IS REPRESENTATIVE PROVIDED BY THE MANUFACTURER. DO NOT MAKE BUYING DECISIONS SOLEY BASED ON THE IMAGE. PLEASE VERIFY SPECIFICATIONS MEET YOUR REQUIREMENTS.

Parker's pilot operated pressure relief valves series R4V OBE (DIN 24340 Form D) and R6V OBE (DIN 24340 Form E) for subplate mounting work stable across the whole pressure range and thus contribute to a smooth-running operation. Additionally they provide a wide range of options and connections for a versatile use in various applications.

The valves operate with a proportional solenoid operated pilot stage with digital electronics which controls a seated type main stage. R4V OBE and R6V OBE are optionally available with a mechanical maximum pressure adjustment.
