Proportional Directional Valve 4WRZ32W8-520-7X/6EG24EK4/M - Bosch Rexroth R901355229

In plants operated across several shifts, an accessible manual override can be moved by accident. The 4WRZ32W8-520-7X/6EG24EK4/M is supplied without auxiliary actuation and is driven purely electrically, at 520 l/min nominal flow.

Benefits

• Version without auxiliary actuation, spool position follows the electrical setpoint alone.
• 520 l/min nominal flow, up to 1600 l/min throughput across 4 ports in size 32.
• Internal pilot oil supply, external return, the pilot stage is relieved through a dedicated line.
• 38 kg weight, spool symbol W8, subplate mounting to ISO 4401-10-09-0-05.
• 350 bar maximum operating pressure using NBR seals and HL hydraulic fluid.

Applications

The valve suits plants where axis movement may come from the controller only, such as automated press lines and installations under a strict access concept. External pilot return matches circuits with a loaded tank channel. An external amplifier at 24 VDC provides the command signal.
