When system pressure fluctuates while the return stays free of pressure, version TK is the right choice. In the 4WRKE25E1-220L-3X pilot oil comes in externally through X and drains internally, and a 4...20 mA current signal supplies the command value. It meters 220 l/min nominal flow at operating pressure up to 350 bar.
Benefits
- External pilot oil supply through X, internal pilot oil return
- 4...20 mA current command value at on-board electronics, 24 V DC
- 220 l/min nominal flow, flow rate up to 870 l/min
- Spool symbol E1, three switching positions, four ports
- 18.4 kg weight, operating pressure up to 350 bar, NBR seals
