Proportional Directional Valve 4WRZE10W9-85-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901015566

Once the pilot circuit is fed by a dedicated pump, the main valve has to route both pilot paths to the outside. This build of the 4WRZE10W9-85-7X does so while metering 85 l/min nominal flow at up to 315 bar.

Benefits

• External pilot oil supply and external return suit power units with a separate pilot pump.
• Pilot pressure stays constant even as working pressure swings up to 315 bar.
• 85 l/min nominal flow in size 10, mounting pattern ISO 4401-05-05-0-05.
• A 4...20 mA command, 24 VDC supply, 7-pole connector (6 + PE) to EN 175201-804.
• Concealed auxiliary actuation, weight 8.47 kg, NBR seals.

Applications

Valves of this build work in press lines and test rigs that keep a separate pilot circuit with filtered oil. The external return stops pressure surges in the working line from reaching the pilot stage. Three switching positions and four ports cover the usual cylinder functions.
