A press brake needs pilot oil from its own source because main pressure collapses during bending. The 4WRKE10W8-100L-3X/6EG24TK31/F1D3M takes pilot oil externally, drains it internally and controls 100 l/min nominal flow.

During bending the main pressure drops briefly and the pilot stage must not notice. The 4WRKE10W8-100L-3X/6EG24TK31/F1D3M therefore draws pilot oil from a separate source and provides 100 l/min nominal flow.
Benefits
- Pilot oil supplied externally, drained internally, pilot pressure survives a load collapse.
- 100 l/min nominal flow, up to 170 l/min in size 10.
- 4...20 mA command with internal spool feedback and a linear characteristic curve.
- 315 bar maximum operating pressure, spool symbol W8, ISO 4401-05-05-0-05 pattern.
- 9.5 kg, NBR seals, HL hydraulic fluid, supplied at 24 VDC.
