When a valve is exchanged, every line that need not be opened counts. The 4WRZ25W6-220-7X/6EG24N9ETK4/V routes pilot oil entirely internally, so only the four main ports meet the manifold, and it meters 220 l/min nominal flow.

Total price
Changing a valve mostly takes long because pilot lines have to be drained and bled again. The 4WRZ25W6-220-7X/6EG24N9ETK4/V avoids that with purely internal pilot routing at 220 l/min nominal flow.
Benefits
- Internal pilot routing in both directions, only the mounting screws have to come loose on exchange.
- 220 l/min nominal flow, maximum flow 870 l/min in size 25.
- Spool symbol W6, 3 switching positions, ISO 4401-08-08-0-05 interface.
- 20.05 kg weight, FKM seals, maximum operating pressure 350 bar.
- Concealed auxiliary actuation, control through external electronics at 24 VDC.

Applications
The variant makes sense in plants with tight maintenance windows, for example continuous production lines. As no pilot lines have to be parted, oil loss during the change stays small. An internal pressure reducing valve is not provided.
