Proportional Directional Valve 4WRZE10W8-85-7X/6EG24K31/A1D3M - Bosch Rexroth R901008733

Where a plant provides its pilot pressure centrally, the 4WRZE10W8-85-7X/6EG24K31/A1D3M works with fully external pilot routing. Supply through X, draining through Y, which decouples the pilot stage from pressure and return of the main circuit. 85 l/min nominal flow and 315 bar operating pressure are available.

Benefits

• External pilot supply and external draining, pilot pressure independent of working pressure.
• 85 l/min nominal flow, maximum flow up to 170 l/min.
• Voltage command value +/-10 V, on-board electronics with position feedback, 24 VDC.
• Operating pressure up to 315 bar, subplate mounting to ISO 4401-05-05-0-05.
• Spool symbol W8, 3 switching positions on 4 ports, weight 8.48 kg.
• NBR seals, hydraulic fluid HL, UKCA conformity.

Application

The valve is built into presses, test rigs and rolling mill axes with their own pilot pressure supply. Separating main and pilot circuit stabilises control behaviour even under strongly varying system pressure. Subplate and piping follow the size 10 mounting pattern.
