Where pilot pressure in the power unit is already limited, a lean pilot stage is enough. The 4WRZE25W9-325-7X/6EG24N9ETK31/F1M works with internal pilot oil supply, internal return and no pressure reducing valve of its own, at 325 l/min nominal flow.
Benefits
- Internal pilot oil supply plus internal return, no X or Y bore in the manifold
- Version without pressure reducing valve in the pilot stage, for an already controlled pilot pressure
- 325 l/min nominal flow in size 25, up to 870 l/min with the corresponding pressure drop
- Command value 4 to 20 mA on the on-board electronics, spool symbol W9 with three switching positions
- 20.4 kg weight, operating pressure up to 350 bar, NBR seals for HL hydraulic fluid
