Proportional Directional Valve 4WRZ32W8-520-7X/6EG24N9EK4/M - Bosch Rexroth R901031137

A size 32 valve controls forces no manual valve can handle and needs a clean pilot stage for that. The 4WRZ32W8-520-7X/6EG24N9EK4/M feeds it internally and relieves it through an external return, at 520 l/min nominal flow.

Benefits

• 520 l/min nominal flow at up to 1600 l/min throughput, carried by 4 ports in size 32.
• Internal supply, external pilot oil return, the pilot stage works against ambient pressure instead of the tank channel.
• 350 bar maximum operating pressure using NBR seals and HL hydraulic fluid.
• Spool symbol W8, concealed auxiliary actuation, setup without power is foreseen.
• 43.2 kg weight, connected through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve serves main axes of forming presses, forging hammers and lock gate drives. External return is the right choice when filters or coolers sit in the tank channel. Operation relies on an external amplifier and a 24 VDC supply.
