Total price
The electronics sit on the valve in the 4WRKE10W6-25L-3X/6EG24EK31/A1D3M, so no external amplifier is needed. The command value ±10 V arrives at the connector, the supply is 24 VDC, and 25 l/min nominal flow is controlled.
Benefits
- Pilot-operated spool valve rated 25 l/min, peaks to 150 l/min.
- On-board electronics handle the command value ±10 V without a separate amplifier.
- Spool with symbol W6, its position measured and corrected internally.
- Pilot oil supplied internally and returned externally, matched to the pilot oil routing of the system.
- Subplate mounting ISO 4401-05-05-0-05 in size 10, to 315 bar.
- 9.36 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Applications
The valve is used in position and force control loops on machine tools, presses and test rigs. 25 l/min nominal flow suits mid-size cylinders whose axis has to follow the command continuously. On a subplate to ISO 4401-05-05-0-05 it replaces an equally wired proportional valve without reworking the piping.
