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

Transcription

1 Characteristics / Technical Data Series PE*W (Parker), RR (Denison) Subplate mounted proportional pressure reducing valves are available with both Parker (series PE*W) and Denison (series RR) 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-00. Features Pilot operated with proportional solenoid Continuous adjustment by proportional solenoid Subplate mounting according to ISO 5781 pressure stages Mechanical maximum pressure adjustment Technical data General Nominal size Interface Subplate mounting acc.
