Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9K31/F1M - Bosch Rexroth R901090238

In widely spread plants a current command and an external pilot circuit often come together because both are provided centrally. The 4WRZE10W8-50-7X/6EG24N9K31/F1M unites exactly these features, regulates 50 l/min nominal flow through spool symbol W8 and works up to 315 bar operating pressure.

Benefits

• Command value 4...20 mA together with external pilot oil supply and external return.
• Nominal flow 50 l/min through spool symbol W8, maximum flow 170 l/min.
• Version without pressure reducing valve, concealed auxiliary actuation on the pilot valve.
• Operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05, size 10.
• Supply voltage 24 VDC, weight 8.01 kg, NBR seals for HL fluid.

Applications

Centrally supplied press lines, rolling mills and test fields feed pilot oil and signals from shared distribution points. The current command stays unambiguous across a hundred metres of cable, the external pilot supply holds the pilot pressure steady. The valve sits in the usual size 10 port pattern.

Manufacturer

Bosch Rexroth lists the valve under R901090238. Type code 4WRZE10W8-50-7X/6EG24N9K31/F1M is decoded in datasheet RE 29115, which also holds characteristic curves and the port pattern, RE 07600-B adds the fluid data.
