5 Tips for Solenoid Valve Maintenance

Regular inspection and maintenance, once or twice a year, is the best way to ensure the solenoid valve reliable work and long service life.
When the solenoid valve is put into operation after the installation or after a long time stop, it needs to inject the medium for several times for test runs. The solenoid valve cannot be placed into service until it works normally.
Before the maintenance, the power supply of solenoid valve must be cut off and the pressure of the medium should be discharged.
The coil components should not be disassembled.
All parts of the solenoid valve should be put in order when the valve is disassembled for cleaning. Thus, it is able to assemble the parts in order after cleaning.
