Reasons for failure of electric valve series

Reasons for failure of electric valve series

    In relatively rare cases, the solenoid valve occasionally encounters the phenomenon that the electric valve does not work after the electric valve is energized. At this time, we don't have to be at a loss. You can implement the self-examination in the following order. I believe it will help immediately.

    1. Whether the power connection is normal or not, re-wire or retry the connection of the connector. The gas solenoid valve prevents the plug from being loose or the power connection is not firm, causing the electric valve to stop working.

    2. Inspect the power supply voltage to confirm whether it is within the allowable positive and negative working range. If there is any change, adjust it in time.

    3. Check the coil, mainly pay attention to whether there is any desoldering phenomenon, if it happens, just re-soldering.

    4. Check the coil to see if there is a possibility of short circuit. Once the high temperature solenoid valve is found, the coil must be replaced.

    5. Observe the working pressure difference. If the pressure difference is too large, immediately adjust the pressure difference until the symmetrical electric valve product is replaced.

    6. Observe the fluid temperature, if the temperature is too high, please replace the corresponding electric valve in time.

    7. Check the main valve core and moving iron core of the electric valve. The magnetic turning column level gauge focuses on checking whether there is any jamming. If necessary, cleaning and cleaning are necessary. If the seal is damaged, the filter should be replaced and installed immediately, because of impurities The possibility of deposition.

    8. Check whether the product is aging, fluid viscosity is too high, and the frequency is too high. In this case, it is recommended to replace the product.

There are many types of electric valves, but when you encounter the above problems, you can follow the above methods. The electric actuators are self-checked in order, and most of the faults should be eliminated. If they can’t be solved anymore, you can turn to the relevant parties. professional.
