Installations with their own pilot pump need a valve that takes pilot oil from outside and returns it outside. This version does exactly that, at 220 l/min nominal flow, spool symbol W6, plus minus 10 V command and 350 bar operating pressure in size 25.

Total price
Where a separate pilot pump holds pilot pressure steady, the valve must neither tap nor drain internally. The 4WRKE25W6-220L-3X/6EG24K31/A1D3M routes both outward and stays independent of working pressure, 220 l/min nominal flow at up to 350 bar.
Key benefits
- External pilot oil supply and external return decouple pilot pressure from working pressure.
- 220 l/min nominal flow, 870 l/min maximum flow, operating pressure up to 350 bar.
- Spool symbol W6 with 3 switching positions and 4 ports, connection pattern ISO 4401-08-08-0-05.
- Analogue control with a plus minus 10 V command, 24 VDC supply, on-board electronics.
- 17.8 kg weight, NBR seals for HL hydraulic fluid, 7-pole connector (6 + PE).
