Stretching units in film lines pull under constant force. The 4WRKE10W8-100L-3X/6EG24EK31/A1D3M controls 100 l/min nominal flow there, takes ±10 V as its command and drains pilot oil through a dedicated return line.

Total price
A stretching unit pulls web material at constant force, so small pressure swings in the return would show up immediately. The 4WRKE10W8-100L-3X/6EG24EK31/A1D3M therefore separates the pilot drain and works with 100 l/min nominal flow.
Benefits
- Pilot oil supplied internally, drained externally, the pilot return stays unpressurised.
- 100 l/min nominal flow, up to 170 l/min in size 10.
- ±10 V command, linear characteristic curve, internal spool position feedback.
- 315 bar maximum operating pressure, spool symbol W8, three switching positions.
- 8.33 kg, ISO 4401-05-05-0-05 pattern, HL hydraulic fluid.
