Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9ETK4/D3M - Bosch Rexroth R900708220

When the amplifier sits apart from the valve, it stays protected from oil temperature and vibration and can be exchanged on its own. The 4WRZ32W6-520-7X/6EG24N9ETK4/D3M is laid out that way and provides 520 l/min nominal flow at a maximum of 350 bar.

Benefits

• Command through external electronics, the controller card stays in the cabinet and can be replaced independently of the valve.
• 7-pole (6 + PE) plug to EN 175201-804, plus a 3-pole (2 + PE) connector on the solenoid.
• 520 l/min nominal flow, up to 1600 l/min throughput, spool symbol W6 in size 32.
• Internal pilot oil supply and internal return with a pressure reducing valve in the pilot circuit.
• 43.42 kg weight, NBR seals, laid out for HL hydraulic fluid at a 24 VDC supply.

Applications

The valve serves presses and lifting gear whose valves sit in a warm or heavily vibrating environment. Because the electronics are separate, a fault is easier to isolate by checking card and valve one after the other. Concealed auxiliary actuation extends that check to the hydraulic side.
