In foundry equipment the return line often carries pressure and the pilot stage should not feel it. The 4WRKE10E1-50L-3X/6EG24EK31/A1D3M takes pilot oil internally, drains it through a dedicated line and controls 50 l/min nominal flow from a ±10 V command.

Total price
Mould and core adjustments travel against changing back pressure. To keep the pilot stage clear of it, the 4WRKE10E1-50L-3X/6EG24EK31/A1D3M drains pilot oil externally and controls its 50 l/min nominal flow from a ±10 V command.
Benefits
- Pilot oil supplied internally, drained externally, back pressure in the main return has no effect on the pilot stage.
- 50 l/min nominal flow at up to 170 l/min, spool symbol E1.
- ±10 V command into the on-board electronics, supplied at 24 VDC.
- 315 bar maximum operating pressure, ISO 4401-05-05-0-05 pattern, three switching positions.
- 9.34 kg, NBR seals, HL hydraulic fluid.
