High tank pressure disturbs the pilot circuit, and a dedicated Y line solves it. The 4WRLE25E400LJ takes pilot oil internally from P, drains it externally and moves 400 l/min nominal flow at 350 bar. Spool symbol E, valve mass 19.34 kg.

In plants with a heavily loaded return line, tank pressure distorts pilot control. The 4WRLE25E400LJ-4X/MPY/24A1 therefore drains pilot oil through its own Y line while controlling 400 l/min nominal flow at 350 bar.
Benefits
- External pilot oil return keeps the pilot circuit free of back pressure in the tank line.
- Internal pilot oil supply saves the X line, as the valve feeds itself from the pressure port.
- 400 l/min nominal flow, maximum flow up to 1250 l/min, operating pressure 350 bar.
- Spool symbol E with a linear characteristic, ±10 V command on on-board electronics.
- CE conformity, 19.34 kg valve mass, mounting pattern ISO 4401-08-08-0-05 in size 25.

Applications
A match for power units where several actuators share one return line and build up back pressure there. Internal pilot supply keeps piping lean as long as system pressure stays above pilot level. For large cylinders the 400 rating supplies flow that smaller nominal sizes can no longer reach.
