(solenoid valve connector)The solenoid does not operate when energized
(solenoid valve connector)Different types of solenoid valves
(solenoid valve connector)Check whether the power wiring is poor → reconnect the wiring and connector
Check whether the power supply voltage is within ± working range - → adjust to normal position range
Whether the coil is desoldered → rewelded
Coil short circuit → replace coil
Whether the working differential pressure is inappropriate → adjust the differential pressure → or replace the corresponding solenoid valve
Fluid temperature too high → replace solenoid valve
The main valve core and moving iron core of the solenoid valve are stuck by impurities → clean. If the seal is damaged, replace the seal and install the filter
The liquid viscosity is too high, the frequency is too high and the service life has reached → replace the product
