Swapping a switching valve for a controlled axis without touching the pipework saves a whole day of conversion. The 4WRZ25W6-325-7X/6EG24N9ETK4/D3M needs nothing but the subplate and the plug. 325 l/min nominal flow, 20.44 kg.

Total price
When moving from a switching valve to a controlled axis the pipework usually stays as it is, provided the new valve asks for no extra ports. The 4WRZ25W6-325-7X/6EG24N9ETK4/D3M meets that, is pilot operated internally and controls 325 l/min nominal flow.
Benefits
- Only subplate and plug are needed, pilot supply and return stay internal.
- Pressure reducing valve in the pilot stage, internal tapping also works at high system pressure.
- 325 l/min nominal flow, flow up to 870 l/min, spool symbol W6 in size 25.
- 20.44 kg weight, 350 bar maximum operating pressure, ISO 4401-08-08-0-05 pattern.
- Concealed auxiliary actuation, 24 VDC through a 7-pole (6 + PE) plug to EN 175201-804.

Applications
This step is typical on older presses and lifting gear whose movements used to be switched hard on and off. The existing ISO 4401-08-08-0-05 subplate is kept, and the amplifier plus its wiring are added. Ramps and end positions can then be driven softly.
