Proportional Directional Valve 4WRZE10W9-50-7X/6EG24N9ETK31/A1D3M - Bosch Rexroth R901220794

A size 10 actuator is driven here at 50 l/min nominal flow. Internal pilot oil supply and internal return mean the manifold only has to carry the four main bores and the mounting threads to ISO 4401-05-05-0-05.

Benefits

• Fully internal pilot stage, the manifold needs only the four main bores
• 50 l/min nominal flow and 170 l/min maximum flow
• Spool symbol W9, 3 switching positions, operating pressure up to 315 bar
• ±10 V analogue command at the on-board electronics, 24 VDC supply
• NBR seals, HL hydraulic fluid, weight 8.46 kg

Applications

It is used in compact manifold controls of machine tools and handling systems. At low system pressure or high tank back pressure a version with external pilot supply is preferable. Concealed auxiliary actuation allows movement without control voltage.
