BS1868 swing check valve prevents the medium in the pipeline from flowing back. The opening and closing parts are opened or closed by themselves by the flow and strength of the medium. Check valves belong to the category of automatic valves, which are mainly used in pipelines where the medium flows in one direction, and only allow the medium to flow in one direction to prevent accidents. This type of valve should generally be installed horizontally in the pipeline. The grinding quality of the sealing surface of the swing check valve directly affects the sealing performance and service life of the valve
By selecting different materials, BS1868 swing check valve can be applied to various media such as water, steam, oil, nitric acid, acetic acid, strong oxidizing media and urea. Mainly used in pipelines of petroleum, chemical, pharmaceutical, fertilizer, power, etc.
