Large flow rates and an independent pilot stage often belong together in presses. The 4WRKE25W8-350L-3X takes pilot oil externally and returns it externally, so the main stage stays under control at 350 l/min nominal flow regardless of load pressure. The command value arrives as ±10 V.
Benefits
- External pilot oil supply and external pilot oil return
- 350 l/min nominal flow, flow rate up to 870 l/min
- ±10 V command value, 24 V DC supply, on-board electronics
- Spool symbol W8, operating pressure up to 350 bar
- 17.92 kg weight, ISO 4401-08-08-0-05 interface
