Pilot Operated Prop. Pressure Relief Valve Series R4V*P2 (Denison)
Catalogue HY11-3500/UK
Characteristics Proportional pressure relief valves series R4V*P2 are based on the mechanically adjusted series R4V. The additional proportional unit between the mechanical pilot valve and the main stage allows continuous pressure adjustment. The optimum performance can be achieved in combination with the digital amplifier module PCD00A-400.
Features • Pilot operated with manual adjustment • Continuous adjustment by proportional solenoid • 2 interfaces - L-body (R4V06-G¾", R4V10-G1¼") - T-body (R4V03-G½", R4V06-G1") • 3 pressure stages • With mechanical maximum pressure adjustment
