Hoists lower their load against the flow and need stable pilot pressure while doing so. The 4WRKE10E1-100L-3X/6EG24TK31/A1D3M draws pilot oil externally, drains it internally and controls 100 l/min nominal flow from a ±10 V command.

Total price
While a load is being lowered the cylinder drives the oil itself and system pressure can fall to almost nothing. The 4WRKE10E1-100L-3X/6EG24TK31/A1D3M therefore takes pilot pressure from a separate source and keeps controlling its 100 l/min nominal flow.
Benefits
- Pilot oil supplied externally, drained internally, the pilot stage stays fed during lowering.
- 100 l/min nominal flow, up to 170 l/min in size 10.
- Spool symbol E1 with internal position feedback and a linear characteristic curve.
- ±10 V command into the on-board electronics, supplied at 24 VDC.
- 8.37 kg, 315 bar maximum operating pressure, ISO 4401-05-05-0-05 pattern.
