Ball valves and butterfly valves are more commonly used valves. Some occasions can be common, and some conditions can only use one of them. The difference between the two lies mainly in the structure and switching principle. Our brief analysis: Ball valve: Plug valve evolved, opening and closing pieces of the ball. Features: 1, low flow resistance; 2, greater pressure and higher temperatures, can be completely sealed; 3, quick opening and closing; 4, the sealing structure determines its comparative and corrosive pick the child; 5, Body symmetry, can effectively withstand the pipeline pressure, high pressure conditions can be dealt with; Butterfly valve: opening and closing pieces are disc-type left and right open. Features: 1, simple structure, small size, easy installation; 2, the flow resistance coefficient is small, quick opening and closing; 3, can be used for large-caliber valves; 4, the application of different sealing surface, using a variety of environments, including powder Shaped, granular media, etc .; butterfly valve relative to the ball valve, slightly less sealing, but the large-diameter valve, the butterfly valve than the ball valve to have a unique advantage; when used to regulate the flow, the butterfly valve adjustment range is not large, accurate. In addition, ball valves have advantages over butterfly valves in high-pressure lines. More Search Keywords: Ball Valve
