Swing flange check valve function is used to prevent backflow of media in the pipeline. Check valve belongs to the automatic valve category, the opening and closing parts rely on the force of the flowing medium to open or close by itself. Check valve is only used for one-way flow of media on the pipeline, to prevent the media backflow, in order to prevent accidents. Swing flange check valve applicable media: water, oil, steam, acidic media, etc., the product is widely used in petroleum, chemical, pharmaceutical, electric power industry and other working conditions of the pipeline.
Swing-type flange check valve is by the flow of the medium itself in the pipeline to generate the force and automatically open and close, belongs to a kind of automatic valve. Check valve is used in pipeline system, its main role is to prevent the media backflow, prevent the pump and its driving motor machine reversal, as well as containers of media discharge. Check valves can also be used to give which the pressure may rise to more than the main system pressure of the auxiliary system to provide supply pipeline.
