Spool symbol W6 and an externally drained pilot flow: this version relieves the pilot stage return through its own line while the supply stays internal. It is driven by integrated fieldbus electronics, and the main circuit provides 400 l/min at 280 bar.

High tank back pressure disturbs the pilot stage, so the 4WRLF25W6-350LJ-4X/MPY00/24ND95 drains pilot oil through an external return while supply remains internal. In size 25 the valve controls 400 l/min nominal flow at 280 bar operating pressure with spool symbol W6.
Key benefits
- Internal pilot oil supply but external pilot oil return for circuits with a loaded tank line.
- Spool symbol W6 with 3 switching positions and 4 ports in size 25.
- 400 l/min nominal flow, up to 1250 l/min maximum flow.
- 280 bar operating pressure at 24 VDC supply voltage.
- Integrated fieldbus electronics on a 7-pole connector (6 + PE) to EN 175201-804.
- 18.58 kg, subplate mounting to ISO 4401-08-08-0-05, NBR seals for HL hydraulic fluid.

Applications
The combination pays off in systems with long or heavily loaded return lines, for example presses sharing one tank. The external pilot drain keeps pressure at the pilot stage steady even when the main return carries a lot of oil. Over the fieldbus several axes can be coordinated with little wiring.
