Proportional Directional Valve 4WRKE10W8-50L-3X/6EG24EK31/A1D3M - Bosch Rexroth R901072595

Constant web tension only comes about when the cylinder follows even a very small command change. The 4WRKE10W8-50L-3X/6EG24EK31/A1D3M achieves that through internal position feedback and 50 l/min nominal flow.

Benefits

• ±10 V command with a linear characteristic curve and fine resolution around zero.
• 50 l/min nominal flow, up to 170 l/min in size 10.
• Pilot oil supplied internally, drained externally, the pilot return stays unpressurised.
• 315 bar maximum operating pressure, spool symbol W8, ISO 4401-05-05-0-05 pattern.
• 8.43 kg, on-board electronics at 24 VDC, 7-pole (6 + PE) plug.

Applications

The valve is used on dancer rolls, winding stations and strip tensioning cylinders in paper, film and metal strip lines. The separate Y drain keeps the pilot stage free of pressure surges from the machine. The command comes from an existing analog card.
