Proportional Directional Valve 4WRZE32W6-360-7X/6EG24N9ETK31/F1D3V - Bosch Rexroth R901210889

Every extra pilot line is another potential leak point. This 4WRZE version in size 32 supplies the pilot stage internally and returns pilot oil internally, so only the standard subplate to ISO 4401-10-09-0-05 is needed. Nominal flow is 360 l/min at up to 350 bar operating pressure, with a 1600 l/min ceiling.

Key benefits

• Fully internal pilot circuit, less piping and fewer sealing points on the manifold
• 360 l/min nominal flow, ceiling 1600 l/min in size 32
• 350 bar maximum operating pressure, spool symbol W6 with 3 switching positions and 4 ports
• 4 to 20 mA current command into the on-board electronics, 24 VDC supply
• 43.76 kg weight, FKM seals, HL hydraulic fluid

Applications

The internal circuit makes sense wherever working pressure stays reliably above the pilot pressure the main spool needs and the tank port carries little back pressure. Compact manifold assemblies in presses and test benches are the usual case. The pressure reducing valve in the pilot circuit caps pilot pressure at the permitted level.
