Total price
Where a separate pilot pump is available but the return line is free of pressure, the TK combination is the right one. The 4WRKE25E1-350L-3X draws pilot oil externally through X and releases it internally, metering 350 l/min nominal flow at operating pressure up to 350 bar. The command value arrives as ±10 V.
Benefits
- External pilot oil supply through X, internal pilot oil return
- Pilot pressure stays independent of the load pressure in the P line
- 350 l/min nominal flow, flow rate up to 870 l/min
- ±10 V command value, 24 V DC supply, 7-pole connector (6 + PE)
- 17.88 kg weight, operating pressure up to 350 bar

Applications
Valves of this kind are used on presses whose system pressure swings widely during the cycle, because the pilot stage can still work at full travel. Spool symbol E1 covers both directions of travel and the centre position. NBR seals match HL hydraulic fluid.
