Spool symbol W6 on size 25: this 4WRZE meters 220 l/min nominal flow at 350 bar, goes without a pressure reducing valve in the pilot stage and routes pilot supply and return inside the valve, which keeps the manifold lean.

Total price
The fewer bores a control manifold needs, the fewer sealing points it can lose. The 4WRZE25W6-220-7X/6EG24N9ETK31/A1V helps that layout because it draws and returns its pilot oil internally while metering 220 l/min nominal flow.
Benefits
- Internal pilot supply and internal return, the manifold needs no pilot bores to the outside.
- 220 l/min nominal flow, up to 870 l/min maximum flow, operating pressure up to 350 bar.
- Build without a pressure reducing valve in the pilot stage.
- Spool symbol W6, three switching positions on four ports, ISO 4401-08-08-0-05.
- Plus/minus 10 V command value, on-board electronics, concealed manual override.
- 20.3 kg, FKM seals, 7-pole connector (6 + PE) to EN 175201-804, UKCA conformity.
