![]() ![]() If the solenoid valve is a plug/socket, there may be problems with the metal reed of the socket (I have encountered it), the wiring on the plug (such as connecting the power cord to the grounding wire), etc. There is a problem with the plug/socket:Įlectromagnetic valve factory solenoid valve failure phenomenon: Treatment method: Replace the solenoid valve coil.Ģ. If it feels magnetic, the solenoid valve coil is good, otherwise it is bad. If the measured resistance is normal (probably tens of ohms), it can not be said that the coil must be good (I once measured a solenoid valve coil resistance of about 50 ohms, but the solenoid valve can not move, after replacing the coil, everything is normal ), please perform the following final test: find a small screwdriver placed near the metal rod in the coil of the solenoid valve, and then energize the solenoid valve. ![]() Short circuit or open circuit of solenoid valve of electromagnetic valve factory:ĭetection method: first measure the on-off with a multi meter, the resistance value approaches zero or infinity, which means that the coil is short-circuited or open circuit. How to detect the short circuit or open circuit of the solenoid valve coilġ. ![]()
