Ball: plug valves evolved, opening and closing parts is the sphere. Features: 1, low flow resistance; 2, the larger the pressure and higher temperatures, can be completely sealed; 3, can quickly open and close; 4, the sealing structure to determine its comparative design and corrosive pick up their kids; 5 body symmetry, can withstand the pressure pipe can cope with high-pressure conditions;
    Butterfly: opening and closing parts are open around disc, characterized by: 1, simple structure, small size, easy installation; 2, the flow resistance coefficient is small, open and close quickly; 3, can be used for large diameter valves; 4 can be applied to different sealing surface, using a variety of environments, including powder, granular media, etc.;
    Relative to the butterfly valve, sealing a bit weak, but the large diameter valves, butterfly valves, ball than to have the unique advantage; as adjust the flow with time, little butterfly adjustment range, and V-type regulating valve, adjustment precision. In addition, high-pressure pipe, ball valve than an advantage.
