At 350 l/min nominal flow this valve belongs on axes with high oil demand. The 4WRKE25W6-350L-3X works with spool symbol W6, processes the ±10 V command value in its on-board electronics and feeds itself with pilot oil internally, so only P, T, A and B need piping.

Total price
Axes with high oil demand call for a pilot-operated valve that passes 350 l/min nominal flow without building a second control circuit. This size 25 proportional valve takes pilot oil internally and returns it internally, regulates the spool to symbol W6 and follows the ±10 V command value up to 350 bar operating pressure.
Benefits
- 350 l/min nominal flow, maximum flow 870 l/min
- Internal pilot oil supply and internal pilot oil return, the four main ports are sufficient
- Spool symbol W6 with a linear characteristic curve and internal spool position feedback
- ±10 V command value, 24 VDC supply, 7-pole (6 + PE) connector to EN 175201-804
- 350 bar operating pressure, FKM seals, weight 17.68 kg
