The wafer butterfly check valve is a kind of valve used to prevent the back flow of the medium in the pipeline and equipment. The butterfly plate adopts the design of two torsion springs on the dual plate to open and close the valve plate within the pressure range. Different types of rubber and other components can be selected according to the needs of users. The length of the valve body structure is short.
