Proportional Directional Valve 4WRZE10E1-85-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R901198231

Two disturbances often appear together: voltage drop on the signal line and back pressure in the tank gallery. This version answers both with a 4...20 mA command value and an externally routed pilot drain, at 85 l/min nominal flow.

Benefits

• 85 l/min nominal flow at 315 bar, maximum flow 170 l/min.
• 4...20 mA command value, immune to interference even on a long cable to the cabinet.
• Internal pilot supply with external drain, so tank pressure has no effect on the pilot stage.
• Pressure reducing valve in the pilot circuit plus a concealed manual override.
• 8.45 kg weight, spool symbol E1, NBR seals, ISO 4401-05-05-0-05 interface.

Applications

Used on presses, test rigs and injection moulding machines with a shared return. The current command value allows large distances between controller and valve. 85 l/min covers rapid and working strokes of a mid range axis.
