Fully separated pilot paths make the 4WRZE25E325-7X/6EG24K31/A1V independent of pressure behaviour and back pressure in the working circuit. The pilot stage is fed through X and relieved through Y, while the main spool with symbol E meters 325 l/min nominal flow and up to 870 l/min at peak.
Benefits
- External pilot oil supply and external return decouple the pilot stage completely.
- 325 l/min nominal flow with a maximum flow rate of 870 l/min at 350 bar.
- Spool symbol E with three switching positions and internal closed loop position control.
- Pilot stage without a pressure reducing valve, supply voltage 24 VDC.
- FKM seals, a valve weight of 20.1 kg and connection diagram ISO 4401-08-08-0-05.
