Total price
In distributed plants the cabinet and the valve often sit far apart. The 4WRKE25W8-220L-3X therefore works with a 4...20 mA command value and takes its pilot oil externally through X, with the drain also routed outside. It meters 220 l/min nominal flow at up to 350 bar.
Benefits
- 4...20 mA current command value for long signal runs
- External pilot oil supply and external pilot oil return
- 220 l/min nominal flow, flow rate up to 870 l/min
- Spool symbol W8, three switching positions
- 17.96 kg weight, operating pressure up to 350 bar, NBR seals
