Solenoid valve failure and troubleshooting-the solenoid valve does not work after it is energized

Check whether the power wiring is bad → re-wiring and connecting the connector


Check whether the power supply voltage is within the ± working range-→ adjust to the normal position range


Whether the coil is unsoldered → re-soldered


Coil short circuit → replace the coil


Whether the working pressure difference is not appropriate → adjust the pressure difference → or replace the commensurate solenoid valve


The fluid temperature is too high → replace the commensurate solenoid valve


Impurities cause the main valve core and moving iron core of the solenoid valve to jam → clean, if the seal is damaged, replace the seal and install the filter


The viscosity of the liquid is too high, the frequency is too high and the service life is up → replace the product
