Fine feed axes need a small nominal flow and electronics that know the spool position. The 4WRKE10W8-25L handles 25 l/min and follows a 4...20 mA current command. Pilot oil is fed in externally and drained externally.

An infeed axis can only be guided as precisely as its nominal flow allows. The 4WRKE10W8-25L-3X/6EG24K31/F1D3M therefore works with 25 l/min nominal flow in size 10 and closes the loop on the spool through internal position feedback against a 4...20 mA command.
Benefits
- 25 l/min nominal flow in size 10, suited to axes that approach short distances accurately.
- 4...20 mA command signal, the current loop stays quiet over long cable runs and a broken wire shows up as 0 mA.
- Pilot oil supplied and drained externally, the pilot stage stays decoupled from the main channel.
- 315 bar maximum operating pressure on the ISO 4401-05-05-0-05 pattern, flow up to 150 l/min.
- Spool symbol W8, 8.42 kg, on-board electronics running at 24 VDC through a 7-pole (6 + PE) plug.
