Proportional Directional Valve 4WRZE32W6-520-7X/6EG24EK31/A1D3M - Bosch Rexroth R901036848

Large flows can be driven from an ordinary analogue output too. The 4WRZE32W6-520-7X accepts ±10 V and turns it into 520 l/min nominal flow, 1600 l/min at peak, at a maximum operating pressure of 350 bar.

Benefits

• Nominal flow of 520 l/min in size 32, connection diagram ISO 4401-10-09-0-05.
• Peak throughput of 1600 l/min for rapid traverse and retraction.
• Voltage command ±10 V, no current output needed in the control system.
• Pressure reducing valve in the pilot stage keeps pilot pressure steady.
• Internal pilot supply, external drain through the Y port.
• Mass of 25 kg with NBR seals, maximum operating pressure 350 bar.

Application

Typical duties are hoists, die cushions and slew drives with a high oil demand. Spool symbol W6 works in three switching positions across four ports. The external pilot drain has to reach tank without back pressure so the pilot stage stays clean.
