Proportional Directional Valve 4WRZ32W6-360-7X/6EG24N9EK4/D3M - Bosch Rexroth R900616528

After a power failure a loaded axis stands still until the spool is moved again. The 4WRZ32W6-360-7X/6EG24N9EK4/D3M allows that through a concealed auxiliary actuation that stays covered in normal operation, and works at 360 l/min nominal flow.

Benefits

• Concealed auxiliary actuation, the spool can be moved by hand after a power failure or during setup.
• 360 l/min nominal flow, up to 1600 l/min throughput, spool symbol W6 across 3 switching positions.
• Internal pilot oil supply, external return, the pilot stage is relieved through a dedicated line.
• Pressure reducing valve in the pilot circuit, control pressure stays limited while the main channel carries up to 350 bar.
• 43.65 kg weight, NBR seals, subplate mounting to ISO 4401-10-09-0-05 in size 32.

Applications

The valve serves presses, lifting gear and lock gate drives where a loaded axis has to be brought into a safe position even without control voltage. The concealed design keeps the actuation from being operated by accident in normal service. An external amplifier at 24 VDC provides the command signal.
