Total price
Large feed axes run more smoothly when the pilot stage hangs on a constant pressure. In version K of the 4WRKE25E1-350L-3X pilot oil is therefore fed in and drained externally, while 350 l/min nominal flow is metered at up to 350 bar. The command value is applied as a ±10 V voltage.
Benefits
- External pilot oil supply and external pilot oil return for constant pilot pressure
- 350 l/min nominal flow, flow rate up to 870 l/min
- ±10 V command value, on-board electronics, 24 V DC supply
- 18 kg weight at operating pressure up to 350 bar
- Spool symbol E1, NBR seals for HL hydraulic fluid
