Not every manifold has a free line for the pilot oil return. This pilot-operated proportional directional valve in size 25 takes its pilot oil from outside and returns it internally, at 350 l/min nominal flow and 350 bar.
Benefits
- External pilot oil supply with internal return saves a separate drain line to tank.
- 350 l/min nominal flow at 350 bar operating pressure, flow up to 870 l/min.
- ±10 V command value on the on-board electronics, spool position fed back internally.
- Spool symbol W8, 3 switching positions, four ports to ISO 4401-08-08-0-05.
- 18.65 kg installed weight, NBR seals, HL hydraulic fluid.
