Small cylinders and swing drives call for fine metering rather than high throughput. This proportional valve with symbol E covers them at 25 l/min nominal flow, fed from a pilot circuit of its own, at 315 bar maximum operating pressure and 7.8 kg.

4WRZ10E25-7X/6EG24N9K4/M supplies and returns pilot oil externally. The pilot circuit therefore sits entirely apart from the working line while the main spool sets actuator speed at 25 l/min nominal flow.
Advantages
- 25 l/min nominal flow for small actuators and fine speed setting
- External pilot oil supply and external pilot oil return
- Symbol E, three switching positions, maximum flow 170 l/min
- Maximum operating pressure 315 bar, size 10, NBR seals
- 7.8 kg mass, HL hydraulic fluid
- Electrical with external electronics, concealed auxiliary actuation
