Proportional Directional Valve 4WRZE10E85-7X/6EG24N9EK31/F1V - Bosch Rexroth R900717050

Large installations bring two sources of trouble together: pick-up on the command line and back pressure in the shared return. The 4WRZE10E85-7X/6EG24N9EK31/F1V answers both, works from 4...20 mA and an external pilot drain, and meters 85 l/min nominal flow at up to 315 bar.

Benefits

• 4...20 mA command value, unaffected by interference along long signal routes.
• Internal pilot oil supply with external pilot oil return, keeping the null point clear of tank pressure.
• 85 l/min nominal flow, maximum flow 170 l/min in size 10.
• Spool symbol E, operating pressure up to 315 bar, connection diagram ISO 4401-05-05-0-05.
• FKM seals, HL hydraulic fluid, 8.48 kg weight.

Applications

Valves of this kind serve rolling mills, mining equipment and large test fields where many axes work into one return manifold. The dedicated pilot drain decouples the pilot stage from neighbouring axes. At 85 l/min there is reserve enough for load changes every few seconds.
