Proportional Directional Valve 4WRZE10W8-50-7X/6EG24N9ETK31/F1M - Bosch Rexroth R901144325

A simulator in a test field has to reproduce motion profiles repeatably, which puts resolution and a clean command signal first. The 4WRZE10W8-50-7X/6EG24N9ETK31/F1M supplies 50 l/min nominal flow through spool symbol W8, accepts the command as 4...20 mA and routes pilot oil supply and return internally.

Benefits

• Spool symbol W8 with 50 l/min nominal flow, maximum flow 170 l/min.
• Command input 4...20 mA on on-board electronics fed from 24 VDC.
• Internal pilot oil supply and internal pilot oil return, pipework limited to four ports.
• Version without pressure reducing valve, with concealed auxiliary actuation.
• Operating pressure up to 315 bar, size 10, weight 8.04 kg.

Applications

Driving simulators, vibration test rigs and shaker tables call for repeatable motion at medium flow. Because both pilot paths run inside the valve, the test set-up stays lean. The subplate mounting to ISO 4401-05-05-0-05 allows an exchange against other size 10 frames.
