Precautions for the Use and Maintenance of Normally Open Solenoid Valves

After being used for a period of time, many of our common normally open solenoid valves will experience sticking, clogging, and loose closing, and the root cause of the problem needs to be found and then analyzed in detail. Today we will talk about the problem of solenoid valve clogging.

1. This is mainly because when the material is discharged, impurities in the pipeline of the 3-position 5-way normally open solenoid valve enter the solenoid valve, causing the valve core to clog, or because the friction force is greater than the spring restoring force, it cannot close or cannot open.

2. Check whether the seal is damaged; if damaged, it should be replaced in time.

3. When the solenoid valve fails, manual valves should be installed before and after it, and a bypass device should be installed to protect the solenoid valve and ensure the normal operation of the system.

4. Check whether there are impurities in the material and whether the old pipeline has detached iron filings, and install a filter element in time.

5. It should be cleaned thoroughly in time, and no residue should be left during cleaning; otherwise, the residue in the SMC normally open solenoid valve will enter the interior of the solenoid valve and cause clogging.

Many people are not familiar with solenoid valves. A solenoid valve is an industrial product used in all walks of life. Now let's talk about some issues to note when using a solenoid valve.

1. When the solenoid valve is not used for a long time, remember to close the valve before closing the manual valve; before restarting the application, remember to clean its interior and then test it again until it works normally.

2. After removing the gas solenoid valve from the pipeline system, be sure to wipe off the various small parts inside it and blow it dry with high-pressure gas before storage.

3. When operating the solenoid valve, be sure to note that the pressure gauge value must not exceed the rated pressure of the valve, and the working pressure of the piston-type normally open solenoid valve must also be kept within the specified range. When the working pressure exceeds the nominal value or the working pressure difference exceeds the nominal value, the solenoid valve should be closed immediately, and the front and rear manual valves should be closed to avoid leakage, explosion, and other situations.

4. The inside and outside of the gate valve and various dirt should be cleaned frequently; when cleaning, take care not to damage its protruding surfaces.
