Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9TK31/F1D3M - Bosch Rexroth R901054349

85 l/min places higher demands on the pilot stage than a small infeed axis does. Pilot oil therefore comes from an external source here, drains internally and is held constant by a pressure reducing valve.

Benefits

• 85 l/min nominal flow, up to 170 l/min maximum flow at 315 bar.
• External pilot oil supply with internal drain, one extra port on the manifold.
• Pressure reducing valve in the pilot circuit, giving repeatable switching times.
• 4...20 mA command value and concealed manual override.
• 8.43 kg weight, spool symbol W8, 3 switching positions, NBR seals.

Applications

Sensible on presses and test rigs where several axes share one tank gallery. The dedicated pilot port keeps dynamics up under load peaks. At 85 l/min the cylinder runs rapid and working strokes from one stage.
