Solenoid faults and troubleshooting FAQs

First, the solenoid valve does not work after power on
Check if the power wiring is bad → Reconnect and connector connections
Check if the power supply voltage is within ± working range - → normal range
Whether the coil is off-welded → re-welded
Short-circuit coil → replace coil
Whether the working pressure difference is not appropriate → adjust the pressure difference → or replace the appropriate solenoid valve
Fluid temperature is too high → replace the appropriate solenoid valve
Impurities have caused the main spool of the solenoid valve and the moving iron core to get stuck → cleaned, and if there is any seal damage, replace the seal and install the filter.
The liquid viscosity is too high, the frequency is too high and the service life is up → Replace the product
Second, the solenoid valve can not be closed
Main spool or iron core seal damaged → Replace seal
Fluid temperature, viscosity is too high → replace the solenoid valve
Impurities enter the solenoid valve core or moving iron core → perform cleaning
Spring life is reached or deformed → replace
Throttle orifice balance plug → timely cleaning
The operating frequency is too high or the service life has expired → Change the product or update the product
Third, other conditions
Internal leakage → Check if the seal is damaged and the spring is not assembled properly
Leakage outside - Loose connections or broken seals - Tighten screws or replace seals
There is noise at the time of power-on → the loose parts on the head are loosened and 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.
