Total price
Before the first coil is energised, the fitter wants to know whether the axis runs free. The 4WRZ25E220-7X/6EG24N9TK4/V can be shifted by its concealed auxiliary actuation for that purpose and meters 220 l/min nominal flow in service.
Benefits
- Concealed auxiliary actuation for setup work and fault finding without power.
- Pilot oil supplied externally, returned internally, so the Y line is not needed.
- 220 l/min nominal flow, with up to 870 l/min passing the main stage.
- 350 bar maximum operating pressure on the ISO 4401-08-08-0-05 interface in size 25.
- 18.2 kg weight, FKM seals, spool symbol E, control through external electronics.
