Proportional Directional Valve 4WRZ32E360-7X/6EG24N9K4/D3M - Bosch Rexroth R901054440

Where pilot oil arrives from outside and leaves outside again, the switching movement no longer depends on the state of the main line. The 4WRZ32E360-7X/6EG24N9K4/D3M adds a pressure reducing valve ahead of the pilot stage and works at 360 l/min nominal flow.

Benefits

• External pilot oil supply and external return, pilot pressure and relief come from a separate circuit.
• Pressure reducing valve in the pilot circuit, control pressure stays inside the permitted range even when supply fluctuates.
• 360 l/min nominal flow, peaks up to 1600 l/min in size 32.
• Spool symbol E, 43.84 kg weight, ISO 4401-10-09-0-05 pattern across 4 ports.
• 350 bar maximum operating pressure using NBR seals for HL hydraulic fluid.

Applications

The valve is used in plants with a central pilot supply feeding several pilot-operated main valves together. Because the return is external as well, a loaded tank channel does not act back on the pilot stage. An external amplifier at 24 VDC takes care of the command signal.
