    Features & Benefits

    SC74 adopts the swing-type structure with small face-to-face dimension, which is widely used and more economical.

    Wafer Swing Check Valve SC74

    A variety of materials are available. It is more suitable for horizontal installation and small diameters. Its shorter length greatly reduces the production and maintenance costs of the check valve.

    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.

    Resilient seat and metal seat can be selected according to the medium.
