API 6D Swing check valve prevents the medium in the pipeline from flowing back. the valve that opens or closes by the flow and force of the medium to prevent the medium from flowing back is called a check valve. 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.
Swing check valve adopts a built-in rocker swing structure. All the opening and closing parts of the valve are installed inside the valve body, and do not penetrate the valve body. Except for the sealing gasket and sealing ring at the middle flange, the whole There is no leakage point, preventing the possibility of valve leakage. The swing arm of the swing check valve adopts a spherical connection structure at the connection between the rocker arm and the valve flap, so that the valve flap has a certain degree of freedom within the range of 360 degrees, and there is an appropriate trace position compensation.
Through the selection of different materials, the 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 such as petroleum, chemical, pharmaceutical, fertilizer, and electric power.
