The injection axis of a moulding machine repeats the same travel thousands of times. The 4WRKE16W6-220L follows the 4...20 mA current command value and passes 220 l/min nominal flow at up to 350 bar. Pilot oil comes in internally, the drain leaves outside.

Total price
The injection axis of a moulding machine runs the same profile thousands of times and must not drift. The 4WRKE16W6-220L-3X/6EG24EK31/F1D3M follows a 4...20 mA current command value, passes 220 l/min nominal flow and holds spool position through internal feedback.
Benefits
- 4...20 mA current command value, the working point survives long cable runs
- 220 l/min nominal flow, maximum flow 460 l/min
- Internal pilot supply with external drain, tank line back pressure does not act on the pilot stage
- 350 bar operating pressure at 10.98 kg
- Spool symbol W6, NBR seals, 24 VDC, size 16
