    Features & Benefits

    SC44 adopts a built-in rocker swing type structure. All the opening and closing parts of the valve are installed inside the valve body without other leakage points.

    Flanged Swing Check Valve SC44

    It is convenient to move and install.

    By opening the valve cover, it’s easy to replace the internal parts of the valve, such as the disc, stem and etc.

    The arm is the connection point between the stem and disc, and its wear resistance and corrosion resistance are the primary factors for material selection.

    The disc is made of pure metal, which features high temperature resistance, high processing precision, wear resistance. And after the disc swings up, it has little influence on the flow of the pipeline.

    The hard metal-to-metal sealing seat can be applied to high temperature and high pressure medium. The seat can be surfacing welding alloy steel or other materials with high wear resistance and corrosion resistance.

    A variety of materials are available. It is more suitable for horizontal installation and large diameters.
