Proportional Pressure Reducing Valves Series PE*W (Parker), R4R (Denison)

Catalogue HY11-3500/UK

Characteristics / Technical Data

Subplate mounted proportional pressure reducing valves are available with both Parker (series PE*W) and Denison (series R4R) model codes. These valves have a proportional solenoid operated pilot stage and a cartridge main stage. The optimum performance can be achieved in combination with the digital amplifier module PCD00A-400. Features • Pilot operated with proportional solenoid • Continuous adjustment by proportional solenoid • Subplate mounting according to ISO 5781 • 4 pressure stages • Mechanical maximum pressure adjustment
