Does not work after power up
Check whether the power wiring is bad → rewire and connect 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 solenoid valve
The fluid temperature is too high → replace the appropriate 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 life is reached → replace the product
Cannot be closed
The seal of the main spool or iron core is damaged → replace the seal
Whether the fluid temperature and viscosity are too high → replace the solenoid valve of the corresponding port
Impurities enter the solenoid valve core or moving iron core → clean
Spring life has reached or deformed → replace
Orifice balance hole blocked → timely cleaning
The working frequency is too high or the service life is up → change the product or update the product
Other circumstances
Internal leakage → check whether the seal is damaged, whether the spring is poorly assembled
External leakage → loose connection or bad seal → tighten the screw or replace the seal
There is noise when energized → The firm part on the head is loose, tighten it. If the voltage fluctuation is not within the allowable range, adjust the voltage. If the suction surface of the iron core is impurity or uneven, clean or replace it in time.
