A ±10 V command together with an external pilot supply is common in machines that have grown over the years and whose control cards should stay in place. This version of the 4WRZE25 covers that case at 220 l/min nominal flow and 350 bar. Spool symbol W6, weight 20.2 kg.

Total price
When a valve is replaced in a machine that has grown over the years, the control card and the pilot piping should stay untouched. This version suits that situation, because it processes the ±10 V command and takes pilot oil externally as well as returning it externally, at 220 l/min nominal flow.
Benefits
- ±10 V command stays compatible with existing analogue outputs and axis controllers.
- Fully external pilot routing matches existing X and Y lines on the manifold.
- 220 l/min nominal flow at 350 bar, 870 l/min at peak.
- On-board electronics make a separate amplifier card unnecessary.
- ISO 4401-08-08-0-05 size 25 interface, weight 20.2 kg.
