    Tips: Reasons for electric actuated wafer butterfly valve leakage

    Electric soft sealing butterfly valve (the raw material of butterfly valve is ductile iron with rubber seal)

    This kind of electric butterfly valve is often used for opening and closing of non-corrosive water at normal temperature.

    Reasons of leakage

    1. The butterfly plate is corroded, due to the ductile iron plate, the valve plate will rust and cause leakage over time.
    2. The rubber valve seat is damaged, the long-term opening and closing, the rubber wear resistance is not good, resulting in the damage of the seal.
    3. The reason for the electric actuator is that the on-site debugging is not in place, resulting in leakage.

    Electric hard seal butterfly valve (the raw material of butterfly valve is carbon steel with metal hard seal)

    This kind of butterfly valve is used in relatively harsh working conditions, generally high temperature steam, heat transfer oil, etc.

    Reasons of leakage

    1. Damage to the sealing surface, caused by high temperature steam cavitation.
    2. The fine and hard particles are washed away for a long time.
    3. The butterfly valve plate has air holes.
