A cylinder should not start abruptly but accelerate steadily. The 4WRA10W30-2X/G24N9K4/V proportional directional valve controls the oil flow for that at a nominal flow of 30 l/min and works with spool symbol W in size 10.

Switching directional valves only know open and closed, which costs precision and loads the mechanics. This directly actuated proportional valve controls direction and rate steplessly, with 30 l/min nominal flow and up to 75 l/min of flow.
Benefits
- Nominal flow 30 l/min at a maximum flow of 75 l/min.
- Spool symbol W with 3 switching positions on 4 ports.
- Directly actuated, giving short response times without a pilot circuit.
- Electrical with external electronics, 24 VDC supply voltage, maximum operating pressure 315 bar.
- Concealed auxiliary actuation for emergency operation without control voltage.
- 5.92 kg weight, subplate mounting ISO 4401-05-04-0-05, FKM seals.
