3. On-Site Fault Maintenance Case
Case: Rexroth Directional Solenoid Valve (4WE 6 J62/EG24N9K4) Failure in Hydraulic Press
Fault Phenomenon: A factory’s hydraulic press experienced misoperation—hydraulic cylinders failed to extend/retract normally. Inspection showed the Rexroth directional solenoid valve (MNR:R900561288, 4WE 6 J62/EG24N9K4) had no response when energized, and the solenoid coil was overheated.
Fault Cause: The factory’s electrical system had voltage spikes, burning the solenoid coil. Additionally, hydraulic fluid contamination caused minor spool jamming, accelerating the valve failure. The maintenance team failed to install a surge protector, leading to voltage instability.
Maintenance Method: Stop the hydraulic press and disconnect the power; replace the failed valve with our genuine Rexroth 4WE 6 J62/EG24N9K4 (MNR:R900561288) with 10% off; install a surge protector to stabilize voltage; clean the hydraulic system and replace the filter; restart the press—operation returned to normal, with precise motion control restored.
