325 l/min nominal flow, a ±10 V command value and an externally routed pilot oil drain describe the 4WRZE25E325-7X/6EG24N9TK31/A1M. At 350 bar operating pressure the pilot stage stays decoupled from return line pressure.

A crowded tank gallery pushes back and degrades the pilot stage. The 4WRZE25E325-7X/6EG24N9TK31/A1M therefore drains its pilot oil separately to tank and meters an undisturbed 325 l/min nominal flow at 350 bar operating pressure.
Benefits
- External pilot oil drain decouples the pilot stage from pressure in the return line.
- 325 l/min nominal flow, peaking at 870 l/min.
- A ±10 V command value at the on-board electronics, fed from an analogue card without a converter.
- Spool symbol E, three switching positions, four ports, ISO 4401-08-08-0-05 mounting pattern.
- 350 bar operating pressure, NBR seals, HL hydraulic fluid, 20.16 kg valve mass.
