Proportional Directional Valve 4WRZ32W6-520-7X/6EG24K4/M - Bosch Rexroth R901407644

In plants where access through the control system is assured, an auxiliary actuation is dispensable. The 4WRZ32W6-520-7X/6EG24K4/M leaves it out and controls 520 l/min nominal flow in size 32.

Benefits

• 520 l/min nominal flow, spool symbol W6, peaks up to 1600 l/min.
• Pilot oil fed in and drained externally, pilot stage kept apart from the main channel.
• 350 bar maximum operating pressure, ISO 4401-10-09-0-05 pattern.
• Driven by external electronics at 24 VDC, 3-pole (2 + PE) plug.
• 43.24 kg weight, NBR seals, HL hydraulic fluid.

Applications

The valve serves main axes of large presses and lifting gear that are moved only through the control system. The separate pilot circuit allows pilot pressure to be sized on its own. Characteristic curves and pilot oil demand are given in the series data sheet.
