Total price
Both pilot oil paths run outside on this version, which fully decouples the pilot stage from the working circuit, at 520 l/min nominal flow on a ±10 V command value.
Key benefits
- External pilot oil supply and return, the pilot stage stays independent of working pressure and tank pressure.
- 520 l/min nominal flow at a maximum flow of 1600 l/min.
- ±10 V command value on a 24 VDC supply, the electronics sit on the valve.
- Spool symbol W8, 4 ports, 3 switching positions, interface ISO 4401-10-09-0-05.
- 44.04 kg, integrated pressure reducing valve, operating pressure to 350 bar, NBR seals.
