Some systems take pilot oil from the main circuit yet return it unpressurised into a line of their own. This size 32 proportional valve is laid out for that case with internal pilot oil supply and external pilot oil return, it passes 360 l/min nominal flow and is driven from external electronics.
Benefits
- 360 l/min nominal flow with a maximum of 1600 l/min across the valve
- Internal pilot oil supply with external pilot oil return, so the Y port runs into a dedicated line
- An integrated pressure reducing valve limits pilot pressure at operating pressures up to 350 bar
- Spool symbol W8, ISO 4401-10-09-0-05 port pattern, weight 42.1 kg
- Concealed auxiliary actuation and FKM seals for HL hydraulic fluid
