Where a central pilot supply feeds several valves, this version does not tap the main gallery at all. Pilot oil supply and drain both run externally, and controlled flow is 50 l/min nominal at 315 bar.

A central pilot supply holds pilot pressure steady even when working pressure collapses. This version makes use of that through external supply and external drain, controlling 50 l/min nominal flow at 315 bar.
Benefits
- External pilot oil supply and external pilot oil drain, keeping pilot pressure independent of working pressure at the 315 bar system rating.
- 50 l/min nominal flow, up to 170 l/min maximum flow.
- No built-in pressure reducing valve, matched to an already regulated pilot circuit.
- FKM seals, ±10 V command value, 24 V DC supply through a 7-pole connector (6 + PE).
- 8.48 kg weight, spool symbol W8, ISO 4401-05-05-0-05 interface.
