Total price
A small pilot power unit of its own delivers constant pilot pressure regardless of what the main circuit is doing. This version is laid out for that and handles 325 l/min nominal flow at 350 bar.
Benefits
- External pilot oil supply and external return, ideal on a separate pilot power unit.
- 325 l/min nominal flow at 350 bar, flow up to 870 l/min.
- Spool symbol E, 3 switching positions, ±10 V command value through the on-board electronics.
- Without a built-in pressure reducing valve, pilot pressure is regulated centrally.
- 20.18 kg installed weight, UKCA declaration, NBR seals for HL fluid.
