Analog cards in older controls deliver the command as a voltage. The 4WRKE10W8-25L-3X/6EG24EK31/A1D3M accepts ±10 V, provides 25 l/min nominal flow and routes pilot oil internally in and externally out.

Total price
Anyone keeping an existing analog card needs a valve with a voltage input. The 4WRKE10W8-25L-3X/6EG24EK31/A1D3M takes a ±10 V command directly, moves 25 l/min nominal flow and reports spool position through internal feedback.
Benefits
- ±10 V command value, sign and magnitude of the voltage set direction and opening of the spool.
- 25 l/min nominal flow at up to 150 l/min in size 10.
- Pilot oil supplied internally, drained externally, the pilot return uses a dedicated line.
- 315 bar maximum operating pressure on the ISO 4401-05-05-0-05 pattern.
- Spool symbol W8, 8.36 kg, on-board electronics at 24 VDC.
