Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R900751839

Two measures raise repeatability noticeably: a pilot drain free of back pressure and a command value transmitted as a current. Both are combined here, at 50 l/min nominal flow with spool symbol W8.

Benefits

• 50 l/min nominal flow at 315 bar, reserve up to 170 l/min.
• Internal pilot oil supply, external drain free of back pressure from the tank gallery.
• 4...20 mA command value, insensitive to cable length and interference fields.
• Pressure reducing valve in the pilot circuit, concealed manual override.
• 8.46 kg weight, spool symbol W8, 3 switching positions, NBR seals.

Applications

Used on test rigs and production plants with high repeatability demands. The external pilot drain needs one additional drilling in the manifold. 50 l/min matches cylinders of medium area at 315 bar.
