Characteristics
Pilot operated proportional pressure relief valves series
R4V (DIN 24340 Form D) and R6V (DIN 24340 Form
E) consist of a proportionally adjusted pilot stage and a
seated type main stage.
The optimum performance can be achieved in combina-
tion with the digital amplifier module PCD00A-400.
Features
• Continuous adjustment by proportional solenoid
• 2 interfaces
- R4V Subplate ISO 6264 (DIN 24340 Form D)
- R6V Subplate ISO 6264 (DIN 24340 Form E)
• 3 pressure stages
• Optional mechanical maximum pressure adjustment
(for R6V)
