Spool symbol W6, 520 l/min nominal flow and a pressure reducing valve in the pilot circuit together define how this axis starts. The 4WRZ32W6-520-7X/6EG24N9EK4/D3M also drains its pilot oil through a dedicated line and withstands 350 bar.

Total price
Starting behaviour, control range and pilot stability rest on three entries in the type designation. On the 4WRZ32W6-520-7X/6EG24N9EK4/D3M these are spool symbol W6, 520 l/min nominal flow and a pressure reducing valve ahead of the pilot stage.
Benefits
- Spool symbol W6 at 520 l/min nominal flow, control range and starting behaviour are fixed by this pairing.
- Pressure reducing valve in the pilot circuit, control pressure stays limited even when the main channel carries 350 bar.
- Internal supply, external pilot oil return, back pressure in the tank channel does not reach the pilot stage.
- Throughput up to 1600 l/min across 4 ports to ISO 4401-10-09-0-05 in size 32.
- 43.66 kg weight, NBR seals, intended for HL hydraulic fluid in an industrial circuit.

Applications
The valve serves main axes of presses, stretching lines and test rigs with high oil demand. Before a replacement, spool symbol and pilot variant of the old part should be compared, because both govern how the axis behaves. Concealed auxiliary actuation allows a check without the electronics connected.
