    Tips: Five tips for solenoid valve maintenance

    1. Regular inspection and maintenance, once or twice a year, is the best way to ensure the solenoid valve reliable work and long service life.
    2. 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.
    3. The power supply of solenoid valve must be cut off and the pressure of the medium should be discharged before the maintenance.
    4. The coil components should not be disassembled.
    5. 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.

    This video shows how ATO 24V DC water solenoid valve is operating internally, and tells you it is a good solenoid valve by testing the solenoid voltage with a multimeter.
