A type of valve that rotates around the centerline of the valve body to open and close the closing element of a clamped thin ball valve. When the pressure of the medium in the chamber of the ball valve exceeds the pre tension force of the spring, the outlet end valve seat retreats and disengages from the ball, achieving automatic pressure relief. After pressure relief, the valve seat automatically resets. The clamped thin ball valve is suitable for general working media such as water, solvents, acids, and natural gas, and is also suitable for media with harsh working conditions such as oxygen, hydrogen peroxide, methane, and ethylene. It has been widely used in various industries.
