Proportional Directional Valve 4WRZE10W8-85-7X/6EG24N9EK31/F1D3M - Bosch Rexroth R900750556

The larger the controlled flow, the more oil also returns through the pilot stage. The external drain keeps it clear of tank pressure here, while the 4...20 mA command value secures the signal path. Nominal flow is 85 l/min.

Benefits

• 85 l/min nominal flow, up to 170 l/min maximum flow at 315 bar.
• External pilot oil drain, internal supply from the pressure gallery.
• 4...20 mA command value, suited to long runs back to the controller.
• Pressure reducing valve in the pilot circuit and concealed manual override.
• 8.45 kg weight, spool symbol W8, NBR seals, ISO 4401-05-05-0-05.

Applications

Found on presses, rolling plants and test rigs with larger cylinders. A separate pilot drain becomes mandatory as soon as several consumers use the same return. Hydraulic fluid is HL and the seals are NBR.
