Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9EK31/A1M - Bosch Rexroth R901063710

During commissioning of a new axis the spool must be movable without electrical power. The 4WRZE10W8-50-7X/6EG24N9EK31/A1M carries a concealed auxiliary actuation on the pilot valve for that, and in service it regulates 50 l/min nominal flow through spool symbol W8 at up to 315 bar operating pressure.

Benefits

• Concealed auxiliary actuation allows a function check and emergency shift without any command signal.
• Spool symbol W8 with 50 l/min nominal flow, maximum flow 170 l/min.
• Internal pilot oil supply with external pilot oil return, no pressure reducing valve.
• Operating pressure up to 315 bar, four ports to ISO 4401-05-05-0-05.
• Analog ±10 V command value, 24 VDC supply, weight 8 kg.

Applications

When special purpose machines and test rigs are built up, the axis is first stroked by hand before the controller takes over. The concealed design of the auxiliary actuation prevents accidental operation during production. On a size 10 manifold the port pattern stays unchanged.
