Proportional Directional Valve 4WRZ32W8-360-7X/6EG24N9ETK4/M - Bosch Rexroth R901490775

Every extra pilot line on a large subplate means a bore, a fitting and one more possible leak. The 4WRZ32W8-360-7X/6EG24N9ETK4/M takes pilot oil internally from the pressure channel and returns it internally into the tank channel, at 360 l/min nominal flow.

Benefits

• Internal pilot oil supply and internal return, the standard subplate is enough, no additional X and Y ports.
• 360 l/min nominal flow at up to 1600 l/min throughput, reserve for rapid traverse phases of large cylinders.
• 350 bar maximum operating pressure using NBR seals and HL hydraulic fluid.
• Concealed auxiliary actuation, setup is possible before the electronics go into service.
• Spool symbol W8, 43.6 kg, connected through a 7-pole (6 + PE) plug to EN 175201-804.

Applications

The valve is used on forming machines and presses whose manifold is already machined and should stay unchanged. Internal pilot routing assumes that system pressure never falls below the required pilot pressure while the axis moves. Control comes from an external amplifier at 24 VDC.
