Total price
In cyclic material testing what matters is that every load cycle looks the same. The 4WRKE10E1-50L-3X/6EG24ETK31/A1D3M supports that with internal position feedback, 50 l/min nominal flow and a ±10 V command.
Benefits
- ±10 V command with a linear characteristic curve, the sign sets the direction of travel.
- 50 l/min nominal flow, up to 170 l/min, spool symbol E1.
- Pilot oil supplied and drained internally, the setup stays free of additional lines.
- 315 bar maximum operating pressure, ISO 4401-05-05-0-05 pattern, size 10.
- 8.33 kg, NBR seals, connected through a 7-pole (6 + PE) plug.
