Total price
When a new valve station is laid out, every line that does not have to be routed counts. The 4WRKE25E220L-3X/6EG24ETK31/A1D3M keeps pilot supply and pilot return internal and therefore needs only the four working ports of the manifold, 220 l/min nominal flow at 350 bar.
Key benefits
- Pilot oil fed and drained internally, no additional pilot lines at the manifold.
- 220 l/min nominal flow in size 25, maximum flow 870 l/min.
- Spool symbol E, 3 switching positions, 4 ports to connection pattern ISO 4401-08-08-0-05.
- Plus minus 10 V command, 24 VDC supply, on-board electronics without an external amplifier card.
- Internal spool position feedback, linear characteristic curve, NBR seals for HL hydraulic fluid.
- 17.9 kg weight, 7-pole connector (6 + PE) to EN 175201-804.

Applications
Sensible wherever a valve station is retrofitted and there is no room for extra pilot lines. At 220 l/min nominal flow the valve serves medium feed and clamping axes. The closed pilot circuit also simplifies later fault finding, because fewer fittings have to be checked.
