If several axes are to react alike, their pilot stages have to hang on the same pressure. The 4WRZ25E325-7X/6EG24N9K4/V is built with an external feed and an external drain for that and meters 325 l/min nominal flow.

Total price
Reproducible switching times across several axes arise only from a uniform pilot pressure. The 4WRZ25E325-7X/6EG24N9K4/V connects feed and drain to the shared pilot circuit and meters 325 l/min nominal flow through spool symbol E.
Benefits
- External feed and external drain, all axes work on the same pilot pressure.
- 325 l/min nominal flow at up to 870 l/min through the main stage.
- Spool symbol E, 3 switching positions, ISO 4401-08-08-0-05 interface in size 25.
- 20 kg weight, FKM seals, 350 bar maximum operating pressure, HL hydraulic fluid.
- No internal pressure reducing valve, with concealed auxiliary actuation.
