Smooth acceleration without a jolt needs a spool that opens finely at the start of travel. This 4WRTE25W6-220L-4X combines spool symbol W6 with 220 l/min nominal flow, works at 350 bar and routes pilot oil internally in both directions.

Benefits
- Spool symbol W6 with 220 l/min nominal flow for graded acceleration
- 870 l/min maximum flow as reserve for rapid traverse
- Internal pilot oil supply and internal pilot oil return
- Analog ±10 V command value, on-board electronics, 7-pole connector to EN 175201-804
- ISO 4401-08-08-0-05 interface, 350 bar operating pressure, NBR seals
