Saw feeds need constant pressure at the pilot stage even as the blade bites into the workpiece. The 4WRKE10E1-50L-3X/6EG24TK31/A1D3M takes pilot oil externally, drains it internally and controls 50 l/min nominal flow from a ±10 V command.

Total price
At the first cut system pressure drops abruptly, yet the feed should stay even. The 4WRKE10E1-50L-3X/6EG24TK31/A1D3M therefore gets its pilot pressure from a separate source and works with 50 l/min nominal flow.
Benefits
- Pilot oil supplied externally, drained internally, pilot pressure does not follow the load change in the main channel.
- 50 l/min nominal flow, up to 170 l/min, spool symbol E1.
- ±10 V command with a linear characteristic curve and internal position feedback.
- 315 bar maximum operating pressure, size 10, ISO 4401-05-05-0-05 pattern.
- 8.3 kg, on-board electronics at 24 VDC, 7-pole (6 + PE) plug.
