Proportional Directional Valve 4WRZ32W6-520-7X/6EG24N9K4/D3M - Bosch Rexroth R900958569

In larger plants a shared pilot supply pays off, because pressure and filtration grade are defined in one place. The 4WRZ32W6-520-7X/6EG24N9K4/D3M ties into that circuit with supply and return and carries 520 l/min nominal flow.

Benefits

• External supply and external return, several main valves can be fed from the same pilot circuit.
• Pressure reducing valve in the pilot circuit, each valve limits its own control pressure regardless of circuit pressure.
• 520 l/min nominal flow, peaks up to 1600 l/min, spool symbol W6 in size 32.
• 350 bar maximum operating pressure, 43.6 kg weight, ISO 4401-10-09-0-05 pattern.
• NBR seals, HL hydraulic fluid, commanded through an external amplifier at 24 VDC.

Technical data

Applications

The valve serves press lines, forging plants and large lifting gear with several controlled axes. Because pilot pressure and filtration grade are fixed centrally, the axes behave evenly relative to each other. Concealed auxiliary actuation allows every axis to be checked on its own.
