Proportional Directional Valve 4WRZE10E1-85-7X/6EG24N9K31/A1M - Bosch Rexroth R901024369

Crane installations often place their valves far from the power unit and feed the pilot stage separately. The 4WRZE10E1-85-7X/6EG24N9K31/A1M is built with external pilot oil supply and external return, regulates 85 l/min nominal flow through spool symbol E1 and is driven by a ±10 V signal.

Benefits

• Nominal flow 85 l/min through spool symbol E1, maximum flow 170 l/min.
• External pilot oil supply and external pilot oil return.
• Version without pressure reducing valve, concealed auxiliary actuation fitted.
• Operating pressure up to 315 bar across four ports to ISO 4401-05-05-0-05.
• Command value ±10 V, 24 VDC supply, weight 8.58 kg, NBR seals.

Applications

Harbour cranes, loading bridges and gantry installations mount valve manifolds right at the drive while pump and pilot oil stay central. The separate pilot paths keep the pilot pressure clear of load peaks in the main circuit. The size 10 port pattern is identical to the other variants.
