  • Product Description
  • Detailed parameters

  • Butterfly check valve is mainly composed of valve body, valve disc, valve stem and spring and other parts, using the clamp connection. Because the valve body closed short stroke, and by the spring loaded, can significantly reduce the water cone phenomenon, the valve is mainly used for urban, industrial and high-rise building water supply, drainage pipe network. Because its structural length is shorter than the general check valve, it is most suitable for places with limited installation space.

    Advantages of wafer butterfly check valve;

    1, simple structure, light weight, especially suitable for low pressure large diameter pipeline;

    2, the clip connection mode, the production process is simple, easy to disassemble;

    3. The check valve adopts wafer type, the butterfly plate is two semicircles, and the spring is used to force the reset. The sealing surface can be the body surfacing wear-resistant material or rubber lining, with a wide range of use and reliable sealing.

    Butterfly check valve is to rely on the medium itself flow and automatically open and close the disc, used to prevent the medium back flow of the valve, also known as check valve, one-way valve, reverse flow valve, and back pressure valve. Check valve is a kind of automatic valve, its main function is to prevent the medium back, to prevent the pump and drive motor reverse, and the discharge of the container medium. The check valve can also be used on the pipeline to supply auxiliary systems where the pressure may rise above the system pressure. Check valve can be divided into swing check valve (rotating according to the center of gravity) and lift check valve (moving along the axis).
