A lean pilot stage is quicker to check and to replace. The 4WRZ10W9-85-7X/6EG24N9TK4/M does without a pressure reducing valve, draws pilot oil externally, returns it internally and controls 85 l/min at 315 bar. Weight 7.7 kg.

Total price
During service what counts is how many parts have to be checked. The 4WRZ10W9-85-7X/6EG24N9TK4/M gets by without a pressure reducing valve in the pilot stage while controlling 85 l/min nominal flow in size 10.
Benefits
- Without a pressure reducing valve in the pilot stage, fewer parts in the pilot oil path.
- External pilot oil supply, internal return, one line fewer at the manifold.
- 85 l/min nominal flow, 170 l/min maximum at 315 bar operating pressure.
- Spool symbol W9, 3 switching positions, 4 ports on interface ISO 4401-05-05-0-05.
- 7.7 kg, 24 VDC, external electronics, NBR seals for HL hydraulic fluid.

Applications
The version is wanted on machines with a tight maintenance window, for instance in series production. A centrally regulated pilot pressure makes a reducing valve inside the valve unnecessary. The large nominal step serves axes with a high travel speed.
