    The difference between centerline butterfly valve and wafer butterfly valve

    Posted by Bundor valve
    Centerline butterfly valve and wafer butterfly valve, I believe that friends who have dealt with valves will not be unfamiliar with the names of these butterfly valves. However, the editor of Bund Valves found that there are still many friends who can't tell the difference between the centerline butterfly valve and the wafer butterfly valve. Some even think that this is a different name for a valve, but it is not. In this article, the editor of BAND Valve will introduce to you what is the difference between the centerline butterfly valve and the wafer butterfly valve?

    The name of the centerline butterfly valve is classified according to the structure of the butterfly valve. In addition to the centerline butterfly valve, there are several types of single eccentric butterfly valve, double eccentric butterfly valve and triple eccentric butterfly valve. This is determined according to the position of the center of the disc in the valve body. The structural feature of the centerline butterfly valve is that the shaft center of the valve stem, the center of the disc and the center of the body are in the same position.
    The centerline butterfly valve has a simple structure and is easy to manufacture. It is usually a soft-sealed valve seat, and the valve seat is made of elastic materials such as rubber or PTFE. The centerline butterfly valve has very good sealing performance and can achieve zero leakage. Due to the limitation of the sealing material itself, the centerline butterfly valve can only be used in the environment of normal temperature and low pressure, and is not resistant to high temperature and high pressure.
    The wafer butterfly valve is named according to the connection method of the butterfly valve.
    Wafer type butterfly valve can be soft seal or hard seal; it can be centerline structure or eccentric structure.
    The centerline butterfly valve can be a wafer type or a flange type.
    The centerline butterfly valve may be a wafer connection, and the wafer butterfly valve may also be a centerline structure.
    Therefore, the centerline butterfly valve and the wafer butterfly valve are two different butterfly valve classifications. In fact, there is no comparison between the two. It is enough to choose the correct butterfly valve form according to different working conditions and environments.
