Total price
When pressure in the tank line swings, repeatability of an internally drained pilot stage suffers. The 4WRKE25W6-220L-3X/6EG24EK31/A1D3M picks up pilot oil internally but drains it separately, holding 220 l/min nominal flow steady at 350 bar.
Key benefits
- Internal pilot oil supply without a second pump, external return against fluctuating tank pressure.
- 220 l/min nominal flow in size 25, maximum flow 870 l/min.
- Spool symbol W6, 3 switching positions, 4 ports, connection pattern ISO 4401-08-08-0-05.
- Plus minus 10 V command into the on-board electronics, 24 VDC supply.
- Internal spool position feedback, linear characteristic curve, NBR seals for HL hydraulic fluid.
- 18.02 kg weight, 7-pole connector (6 + PE) to EN 175201-804.

Applications
The variant proves itself on plants with many consumers working in parallel, where returns build up against each other. Because pilot oil drains separately, the null position of the spool stays reproducible. At 220 l/min nominal flow the valve fits feed and positioning axes of medium power.
