In an accumulator circuit the pump runs without pressure at times, yet the axis should stay controllable. The 4WRZ10W8-50-7X/6EG24N9K4/D3M routes pilot oil entirely externally and controls 50 l/min at 315 bar.

Total price
Anyone running an accumulator has phases without pump pressure. The 4WRZ10W8-50-7X/6EG24N9K4/D3M therefore draws its pilot oil from a dedicated source and stays controllable throughout at 50 l/min nominal flow.
Benefits
- External pilot oil supply and external return, controllable even with an unloaded main circuit.
- 50 l/min nominal flow, up to 170 l/min flow at 315 bar.
- Spool symbol W8 with 3 switching positions, 4 ports to ISO 4401-05-05-0-05.
- Pressure reducing valve in the pilot stage and concealed auxiliary actuation.
- 8.28 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.
