Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9K31/F1D3M - Bosch Rexroth R901094002

When both working pressure and tank pressure fluctuate, a separate pilot oil supply is the remaining route. This version takes supply and drain externally and controls 85 l/min nominal flow from a 4...20 mA command value.

Benefits

• External pilot oil supply and external pilot oil drain, independent of working and tank pressure.
• 85 l/min nominal flow, 170 l/min maximum flow at 315 bar.
• 4...20 mA command value, robust against line resistance and electrical interference.
• Pressure reducing valve in the pilot circuit and concealed manual override.
• 8.49 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.

Applications

Built for multi-axis plants with their own pilot power unit and long signal runs. Test rigs and large presses benefit from the stable pilot stage. At 85 l/min a mid range size 10 axis is well served.
