When system pressure swings, a built-in pressure reducing valve keeps pilot pressure constant. This version of the 4WRZE 10 combines that with 85 l/min nominal flow, spool symbol E1 and a concealed manual override.

Total price
A pilot circuit that follows system pressure changes the switching time of the main spool. The built-in pressure reducing valve prevents that, and the concealed manual override still allows the axis to be moved without power. Nominal flow is 85 l/min at 315 bar.
Benefits
- Pressure reducing valve in the pilot circuit, holding pilot pressure steady even at 315 bar system pressure.
- Concealed manual override for commissioning and faults without the 24 V DC supply.
- 85 l/min nominal flow, up to 170 l/min maximum flow.
- Internal pilot oil supply, external pilot oil drain, spool symbol E1 with 3 switching positions.
- 8.4 kg weight, NBR seals, ±10 V command value, ISO 4401-05-05-0-05 interface.

Applications
Suited to axes whose system pressure drops sharply within the cycle, for example on presses with a rapid and a pressing stroke. The manual override helps during setup and when freeing the machine after a fault. The external pilot drain keeps the pilot stage clear of tank pressure.
