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
