First, the solenoid valve does not work after power on Check the power wiring is not bad → re-wiring and connector connection Check the power supply voltage is ± working range → → normal position range to adjust the coil is not welded → re-weld coil short circuit → replace coil working pressure The difference is not suitable → adjust the pressure difference → or replace the appropriate solenoid valve fluid temperature is too high → replace the solenoid valve with impurities so that the main valve plug and the moving iron core solenoid valve stuck → cleaning, if there is a seal damage should be replaced Sealed and installed filter liquid viscosity is too high, the frequency is too high and life has expired → replace the product Second, the solenoid valve can not close the main valve core or the iron core seal is damaged → replace the seal fluid temperature, viscosity is too high → Replace the solenoid valve of the counterpart Impurities enter the solenoid valve Production spool or moving iron core → Perform cleaning Spring life is reached or deformed → Replace throttle hole Balance hole plugging → Timely cleaning Working frequency is too high or service life is reached → Reselect product or update Product III. Leakage in other situations → Check if the seal is damaged, if the spring is badly assembled, if it leaks outside, → the connection is loose or the seal is broken → Tighten the screw or replace the seal. There is no noise when the power is turned on. → The loose solid on the head is tightened. The voltage fluctuation is not within the permissible range and the voltage is adjusted. Core suction surface impurities or uneven, timely cleaning or replacement.
