What the axis does without a command value is set by the spool symbol. The 4WRZ10W8-85-7X/6EG24N9TK4/D3M uses symbol W8, controls 85 l/min nominal flow at 315 bar and draws its pilot oil from an external source.

Total price
In centre position the spool geometry decides whether the cylinder holds or is relieved. The 4WRZ10W8-85-7X/6EG24N9TK4/D3M uses spool symbol W8 for that and controls at 85 l/min nominal flow in size 10.
Benefits
- Spool symbol W8 with 3 switching positions, a defined arrangement of the 4 ports without a command value.
- 85 l/min nominal flow, 170 l/min maximum flow at 315 bar.
- External pilot oil supply, internal return, with a pressure reducing valve in the pilot stage.
- Electrical with external electronics, 24 VDC, 7-pole plug (6 + PE) to EN 175201-804.
- 8.19 kg, NBR seals, HL fluid, subplate mounting to ISO 4401-05-05-0-05.

Applications
The application is on axes that should take a defined oil path when de-energised. The large 85 l/min step suits cylinders with a high travel speed. External pilot supply keeps the pilot stage working even while the main circuit is unloaded.
