Well known as excellent pressure relief valves, Parker's series R4V/R6V and R4V/R6V Proportional 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.

Pilot operated pressure relief valves series R4V (DIN 24340 Form D) and R6V (DIN 24340 Form E) consist of a manually or a proportionally adjusted pilot stage and a seated type main stage. A vent function with a solenoid operated directional valve is available for circulation at minimum pressure. The optimum performance of the proportional version can be achieved in combination with the digital amplifier module PCD00A-400.

    - R4V Subplate ISO 6264 (DIN 24340 Form D) with VV01 vent valve
    - R6V Subplate ISO 6264 (DIN 24340 Form E) with CETOP 03 vent valve
• 3 pressure stages
• 3 adjustment modes:
    - hand knob
    - acorn nut with lead seal
    - cylinder lock
• Remote control via port X
• Mechanical maximum pressure adjustment (optional for R6V*P2)

Applications:
• Suitable for general hydraulic applications
• General presses
• Die cast

Function:
Series R4V/R6V
System pressure in port P is applied via the X gallery to the spring loaded cone in the pilot head. The pilot head controls the pressure in the Z area on top of the main cartridge which is additionally kept close by the main spring.
If the pilot pressure exceeds the setting pressure the pilot cone opens and thus limits the pilot pressure. When the system pressure exceeds the pilot pressure plus the spring force, the main cartridge opens to port T and limits the pressure in port P to the adjusted level.

Series R4V/R6V with vent function
Additionally to the relief function, a solenoid operated vent valve connects the Z area to tank. This allows oil circulation from P to T at minimum pressure drop. The vent valve can either be a standard CETOP 03 valve (R6V) or a sandwich unit (R4V). For both types the vent position can be either at the energized or de-energized solenoid.
