Total price
Press tools record every jerk of the infeed axis in the part. The 4WRZE10E25-7X/6EG24K31/A1D3V therefore keeps flow stepless at 25 l/min rated value and 315 bar maximum operating pressure, while the pilot stage is fed through a pressure reducing valve of its own.
Benefits
- Pressure reducing valve in the pilot stage keeps pilot supply independent of working conditions.
- External pilot oil supply and external pilot oil return, suited to circuits that carry a separate pilot pump.
- 25 l/min rated flow, up to 170 l/min at the corresponding differential.
- Spool symbol E, three switching positions, operating limit 315 bar, port pattern ISO 4401-05-05-0-05.
- Command value 10 V bipolar into the on-board electronics, 24 VDC supply, 9 kg, FKM seals for HL fluid.

Application
The valve goes into infeed and feed axes of presses, straightening machines and forging lines. Because the pilot oil comes from outside, the pilot stage stays alive even when working conditions collapse during the cycle. The same axis driven by a current signal is served by the F1 build.
