Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9TK31/F1D3M - Bosch Rexroth R901071135

Piping effort often decides assembly time more than the valve itself. This version needs one external pilot feed, the drain is handled by the tank gallery of the manifold, and the command value arrives as a 4...20 mA current.

Benefits

• 50 l/min nominal flow, 170 l/min maximum flow at 315 bar.
• External pilot oil supply with internal drain, so one extra line is all that is added.
• 4...20 mA command value for long distances between controller and valve.
• Pressure reducing valve in the pilot circuit, concealed manual override.
• 9.12 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05 interface.

Applications

Built into control manifolds that carry a dedicated pilot line and collect the return. Constant pilot pressure gives repeatable ramp times. 50 l/min matches cylinders of medium area.
