Total price
Not every power unit with a pilot pump also has a separate pilot drain. For that case the 4WRZE25W9-220-7X/6EG24N9TK31/A1D3M discharges pilot oil internally while being supplied from outside, at 220 l/min nominal flow in size 25.
Benefits
- External pilot oil supply with internal return, matching manifolds without a separate drain channel.
- 220 l/min nominal flow, 870 l/min maximum flow, operating pressure up to 350 bar.
- Pressure reducing valve in the pilot circuit for constant pilot pressure.
- Symbol W9 with three switching positions and concealed auxiliary actuation.
- Command value ±10 V DC, weight 20.8 kg, 7-pole connector (6 + PE) to EN 175201-804.

Applications
The valve suits retrofitted axes in presses and lifting gear whose existing manifold provides no external pilot drain. External supply secures pilot pressure even when system pressure is low. For plants with a fully internal pilot circuit the same range offers a matching alternative.
