The applicable media are water, oil products, steam and acid media. It is a valve that controls the one-way flow direction of medium in the pipeline to prevent the backflow of medium in the pipeline. Check valves are automatic valves, and the opening and closing parts open or close by the force of flowing medium. The check valve is only used on the pipeline with one-way medium flow to prevent medium backflow and prevent accidents. It is mainly used in petroleum, chemical, pharmaceutical, chemical fertilizer, electric power and other pipelines.
