A characteristic curve with a fine control range resolves small command changes around mid position more finely. The 4WRKE25W8-220P-3X brings that curve to size 25, passes 220 l/min nominal flow and accepts a 4...20 mA command value.

Large axes should travel fast and still be finely adjustable around zero, and that is exactly what the linear characteristic curve with fine control range is made for. This pilot-operated size 25 proportional valve passes 220 l/min nominal flow, regulates the spool through internal position feedback and evaluates the 4...20 mA command value in its on-board electronics.
Benefits
- Linear characteristic curve with a fine control range, spool symbol W8
- 220 l/min nominal flow, up to 870 l/min across the valve
- 4...20 mA command value, 24 VDC supply, on-board electronics at the valve
- External pilot oil supply and external pilot oil return
- NBR seals for HL hydraulic fluid, operating pressure up to 350 bar
- Subplate mounting to ISO 4401-08-08-0-05, weight 17.8 kg
