When pilot oil comes from a separate circuit held at constant pressure, valve dynamics stay independent of load pressure. This size 25 4WRTE uses external supply and external return and meters 350 l/min at 350 bar through spool symbol E1.

Total price
A strongly varying system pressure drags the pilot stage down with it. This pilot-operated proportional directional valve in size 25 therefore takes pilot oil externally and drains it externally, while the main circuit carries 350 l/min nominal flow at 350 bar.
Benefits
- External pilot oil supply and external return keep the pilot stage away from varying load pressure.
- 350 l/min nominal flow at 350 bar, up to 870 l/min flow in size 25.
- Spool symbol E1 with 3 switching positions across four ports.
- ±10 V command value, on-board electronics, internal spool position feedback.
- 17.90 kg installed weight, NBR seals for HL hydraulic fluid.
