The solenoid valve connector cannot be closed
(solenoid valve connector)The seal of the main valve core or iron moving core is damaged → replace the seal
(solenoid valve connector)Whether the fluid temperature and viscosity are too high → replace the corresponding solenoid valve
(solenoid valve connector)Impurities enter the valve core or moving iron core of solenoid valve → clean
Spring life expired or deformed → replace
The orifice and balance orifice are blocked → clean them in time
The working frequency is too high or the service life has reached → change the product or update the product
Other situations
Internal leakage → check whether the seal is damaged and whether the spring is poorly assembled
External leakage → loose connection or damaged seal → tighten the screw or replace the seal
There is noise during power on → the fasteners on the head are loose and tightened. The voltage fluctuation is not within the allowable range. Adjust the voltage. Clean or replace the iron core timely in case of impurities or unevenness on the suction surface of the iron core.
