Proportional Directional Valve 4WRZE10E1-50-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901124428

Stage and platform hydraulics ask for quiet, even travel at a medium oil demand. The 4WRZE10E1-50-7X/6EG24N9ETK31/F1M regulates 50 l/min nominal flow through spool symbol E1, follows a 4...20 mA current command and places pilot oil supply and return inside the valve.

Benefits

• Nominal flow 50 l/min through spool symbol E1, maximum flow 170 l/min.
• Internal pilot oil supply and internal return, pipework limited to four ports.
• Command value 4...20 mA on on-board electronics, 24 VDC supply voltage.
• Version without pressure reducing valve, concealed auxiliary actuation for emergency operation.
• Operating pressure up to 315 bar, size 10, weight 8.76 kg.

Applications

Lifting platforms, stage wagons and orchestra pit lifts run on limited flow with long holding periods. The concealed auxiliary actuation makes it possible to lower an axis in a controlled way during a power failure. On the size 10 manifold the port pattern to ISO 4401-05-05-0-05 is retained.
