Why doesn’t the solenoid valve close when power is lost?
Thread Content
When there is no pressure inside the device, the switch works normally, but it won’t turn off after the device is turned on. What’s going on?
Is there a manual switch button on the solenoid valve?
There’s a manual method: after removing the solenoid coil, the solenoid will work properly again with a little care.
The spool inside the solenoid valve is a bit stuck; it’s best to take it out, open it up, and clean it
Is the air in your instrument panel contaminated with a lot of impurities?
Get a new one; it will be the same situation in the future.
This has never happened before.
Over time, it gets dirty inside, and the spool can easily get stuck
The interlock must be engaged. . . . . .
Check whether the cylinder piston rings need to be replaced. The inspection should be carried out by introducing instrument air on one side and atmospheric air on the other side to check for any leaks. Try both sides. Another situation is when the piston rings age and become stuck. This is related to the cylinders. The inspection of solenoid valves involves cleaning them and then blowing them clean with compressed air. The internal passages of the valve are unobstructed and free of impurities. I’m not sure what the structure of your solenoid valve is, or whether the rubber components inside it are damaged. What is the status of the power-loss reset spring??? Also, items such as lubricating oil, filters, and pressure relief valves need to be checked and maintained over time; it’s best to ensure that any problems are resolved.
