The fluorine-lined vertical check valve H42 is an automatic valve whose main function is to prevent the backflow of the medium. This valve relies on the flow of the medium itself to automatically open or close the valve disc to prevent the reverse flow of the medium. The H42 type fluorine-lined vertical check valve is a vertically installed valve. Its structural feature is that the fluorine-lined valve disc moves up and down perpendicular to the inlet and outlet axes of the valve body, and has very good sealing performance.
