The disc rotates around the pin outside the seat to open or close the valve; It is automatically opened and closed by the force generated when the medium flows in the pipeline, which belongs to an automatic valve. The main function is to prevent the backflow of the medium in the pipeline, prevent the reversal of the pump and its drive motor, and the drainage of the medium in the container.
