Total price
At 520 l/min nominal flow an axis moves a lot of oil in a short time, and the pilot stage has to follow that movement cleanly. The 4WRZ32W6-520-7X/6EG24N9TK4/D3M combines external pilot oil with a built-in pressure reducing valve for that.
Benefits
- 520 l/min nominal flow, up to 1600 l/min throughput across 4 ports in size 32.
- Pressure reducing valve in the pilot circuit, the pilot stage works independently of the pressure in the main channel.
- External pilot oil supply, internal return, suited to plants with a central pilot circuit.
- Spool symbol W6, 43.56 kg weight, subplate mounting to ISO 4401-10-09-0-05.
- 350 bar maximum operating pressure, NBR seals, laid out for HL hydraulic fluid.
