Screwdown cylinders in a rolling mill move a few tenths under high force. The 4WRKE10E1-100L-3X/6EG24EK31/A1D3M controls them with 100 l/min nominal flow, is guided by ±10 V and drains its pilot oil through a dedicated line.

Total price
A screwdown cylinder has to move a few tenths of a millimetre while rolling force pushes back. The 4WRKE10E1-100L-3X/6EG24EK31/A1D3M keeps control quiet because the pilot drain stays separate from the main return.
Benefits
- Pilot oil supplied internally, drained externally, pressure surges in the main return never reach the pilot stage.
- 100 l/min nominal flow, up to 170 l/min, spool symbol E1.
- ±10 V command with a linear characteristic curve and internal spool feedback.
- 315 bar maximum operating pressure in size 10, three switching positions.
- 8.34 kg, NBR seals, connected through a 7-pole (6 + PE) plug.
