Pilot Operated Pressure Relief Valves
Series RE*W (Parker), R*V (Denison)

Characteristics
Proportional pressure relief valves for external electronics
are available with both Parker (series RE*W) and Denison
(series R*V) model codes.
A proportionally adjusted pilot stage controls a seated
type main stage. The valves are equipped with a mechani-
cal maximum pressure stage (optional for RE*R*W).
The optimum performance can be achieved in combina-
tion with the digital amplifier module PCD00A-400.
Features
• Pilot operated with proportional solenoid
• Continuous adjustment by proportional solenoid
• 2 interfaces: subplate, ISO 6264 (DIN 24340 Form D
+ Form E)
• 4 pressure stages
• Optional mechanical maximum pressure adjustment
(for RE*R*W)
