STRUCTURAL DESIGN: It may adopt a swing-type structure, where the valve disc is connected to the valve body through a hinge mechanism and can rotate around an axis to open and close. This structure is relatively common in large-diameter valves. It enables the valve disc to have sufficient swing space when opening, and the fluid encounters relatively low resistance when passing through. It may also be a lift-type structure, where the valve disc slides along the vertical centerline of the valve body and opens and closes relying on the pressure of the medium. This type has better sealing performance.
