The Size Range of Floating Ball Valves

Floating ball valves are extremely widely used in industrial and civil fields. Their size range plays a crucial role in adapting to different pipeline systems and working conditions. In terms of nominal diameter, the nominal diameter of common floating ball valves generally ranges from DN15 to DN250 (1/2 inch to 10 inches). For example, in small household or laboratory pipeline systems, small sized floating ball valves such as DN15 and DN20 are more common and are used to precisely control the flow of a small amount of liquid or gas. In the large pipeline networks of industrial plants, large sized floating ball valves such as DN200 and DN250 undertake the tasks of cutting off and regulating the flow of large volume media.

In practical application scenarios, chemical enterprises will select floating ball valves made of corrosion resistant materials for their pipeline systems due to the corrosive nature of the transported medium. According to the pipeline layout and flow requirements, ball valves with smaller diameters such as DN15 and DN40 may be selected for branch pipelines, while large sized ball valves such as DN150 and DN200 are used for main pipelines. In urban gas transmission pipe networks, to ensure stable gas supply, large diameter floating ball valves such as DN200 and DN250 are used for cutting off the gas source in main roads, and small diameter ball valves such as DN50 and DN80 are used for controlling the household pipelines in residential areas.
