Proportional Directional Valve 4WRZE10W6-85-7X/6EG24EK31/F1D3M - Bosch Rexroth R901004023

Adjusting a calender roll from a current interface calls for a valve with the matching command input. The 4WRZE10W6-85-7X/6EG24EK31/F1D3M pairs 4...20 mA control with spool symbol W6, carries 85 l/min nominal flow and draws its pilot oil internally.

Benefits

• Current command 4...20 mA on on-board electronics fed from 24 VDC.
• Spool symbol W6 with three switching positions and 85 l/min nominal flow.
• Internal pilot oil supply, external pilot oil return, pressure reducing valve in the pilot circuit.
• Maximum operating pressure 315 bar, maximum flow 170 l/min.
• Subplate mounting ISO 4401-05-05-0-05, 8.44 kg weight, NBR seals.

Applications

Paper machines, film lines, coating plants and winders adjust their rolls through axes of this kind. The current command stays unambiguous even when valve and controller sit dozens of metres apart. On a size 10 manifold the valve keeps the familiar port pattern.
