Problems with electric valves
Thread Content
There is a 220V electric valve that works fine when powered on, but loses power as soon as a switch is activated. What is the likely cause of this issue?
Remove the load and use a meter to find out exactly where the problem lies
There are various reasons for this; electric valves come equipped not only with current protection but also with torque protection. Check to see if the electric valve is stuck in some position
There are many reasons; the electrical circuit, actuators, and valve body all need to be checked one by one
It seems that the switch has a short circuit problem...
This kind of thing has happened here before; upon inspection, it turned out to be a problem with the motor, and in the end, the electrical department was called in to fix it!
Too many problems. In general, it is said that the current exceeds the allowable current of the circuit breaker, which means current overload. There are many reasons for excessive current in electric motors; one can think about these on their own. It could also be that the circuit breaker used is too small, or that the load connected to the breaker is too heavy, which leads to overload during the operation of the electric valve.
