When several valves work into the same return manifold, pressure builds up there. This 4WRTE25W6-350L-4X therefore drains its pilot oil separately while taking it internally. Nominal flow 350 l/min, operating pressure 350 bar, ±10 V command value.

Shared return manifolds in large control blocks carry changing counter pressure that affects the pilot stage. This 4WRTE25W6-350L-4X decouples itself through an external pilot drain while taking pilot oil internally from working pressure, at 350 l/min nominal flow.
Benefits
- External pilot drain against counter pressure in a shared return manifold
- Internal pilot oil supply, one feed line less
- 350 l/min nominal flow, 870 l/min maximum flow
- Spool symbol W6, three switching positions, four ports
- Analog ±10 V command value, ISO 4401-08-08-0-05 interface, 350 bar operating pressure

Applications
Sensible on large manifolds with many axes working in parallel, for example press lines and steel plant equipment. The separate pilot drain keeps switching behaviour independent of what neighbouring axes push into the return. The 350 l/min nominal flow also serves large cylinders.
