The efficiency and safety of fluid systems directly affect the operation of production processes and equipment. A ball valve is a common valve that is mainly used to cut off, distribute, and change the flow direction of fluid media in pipelines. A ball valve generally used to connect to a water pump is called a pump ball valve. Existing ball valves may experience backflow during use, which may cause equipment damage, fluid contamination, and safety hazards.
