Proportional Directional Valve 4WRZE10W8-85-7X/6EG24EK31/A1V - Bosch Rexroth R900758293

A loaded tank gallery acts straight back on the pilot stage. Pilot oil is therefore drained separately to the outside here, while the supply is taken from the main gallery. Nominal flow is 85 l/min at 315 bar operating pressure.

Benefits

• 85 l/min nominal flow, 170 l/min maximum flow in size 10.
• Internal pilot supply with external drain, so tank pressure does not act on the pilot stage.
• Version without a pressure reducing valve, rated for 315 bar operating pressure.
• FKM seals and ±10 V command value with on-board electronics.
• 8.42 kg weight, spool symbol W8, ISO 4401-05-05-0-05 interface.

Applications

Used on presses and power units where several axes share one return line. The separate pilot drain keeps the null position stable under load peaks. At 85 l/min the axis is sized for rapid and working strokes.
