A feed axis has to resolve finely although the tank gallery carries back pressure. The 4WRZ10E25-7X/6EG24N9EK4/D3V meters a nominal flow of 25 l/min and takes the pilot return outside, with an internal supply. 315 bar, spool symbol E, 8.24 kg.

At 25 l/min nominal flow an axis can be advanced very finely. So that back pressure in the tank gallery does not disturb the pilot stage, the 4WRZ10E25-7X/6EG24N9EK4/D3V routes the pilot return outside while the supply stays internal.
Benefits
- 25 l/min nominal flow at a maximum flow of 170 l/min.
- External pilot return with internal supply, independent of back pressure in the return line.
- Spool symbol E with 3 switching positions across 4 ports.
- 315 bar operating pressure in size 10 to ISO 4401-05-05-0-05.
- 8.24 kg with FKM seals, driven by external electronics on 24 VDC.
