Proportional Directional Valve 4WRZE25W9-325-7X/6EG24N9ETK31/F1D3M - Bosch Rexroth R900785482

Interference resistant signalling and a power unit without a pilot pump can be brought together in one valve. The 4WRZE25W9-325-7X/6EG24N9ETK31/F1D3M runs on 4 to 20 mA, supplies itself internally and controls 325 l/min nominal flow in size 25.

Benefits

• Current command value 4 to 20 mA, robust against interference and voltage drop.
• Internal pilot oil supply and internal return, with no additional pilot line.
• 325 l/min nominal flow, 870 l/min maximum, operating pressure up to 350 bar.
• Pressure reducing valve and concealed auxiliary actuation are part of this version.
• Weight 20.78 kg, symbol W9, mounting pattern ISO 4401-08-08-0-05, NBR seals.

Applications

The valve makes sense in plants with long cable runs between control cabinet and hydraulic manifold, for example rolling mills and large press lines. Because piloting is internal, the hydraulic schematic stays clear. Concealed auxiliary actuation allows controlled movement during a power failure.
