The main characteristic of ball valve is itself compact and easy to operation and maintenance, suitable for water, solvents, acid and natural gas generally work medium, and also applies to working conditions of the bad medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. Ball valve body can be whole, also can be combined. Ball valve is mainly used to do on lines cut off, distribution and change flow direction of medium. Ball valve is widely used in recent years is a new type of valve, fluid resistance small, the resistance coefficient and the length of the pipeline section with equal.

Ball valve simple structure, small volume, light weight. Close, the ball valve sealing surface of reliable material widely used in plastic, good sealing, vacuum system also has been widely used. Easy operation, open and close rapidly, from full open to seated as long as 90 °, facilitate rotating long distance control. Easy maintenance, ball valve structure simple, sealing ring is usually activities, remove the change are more convenient. In the fully open or fully closed, the ball and the seat of the fore and medium isolation, media through the, not cause of valve sealing surface erosion. Wide range from a few millimeters to size, to a few meters from the high vacuum and high pressure can apply.

Usually the most appropriate do think ball valve directly use open and close, but recent development has designed to make it has ball valves and control flow with the throttle. The main characteristic of ball valve is itself compact and easy to operation and maintenance, suitable for water, solvents, acid and natural gas generally work medium, and also applies to working conditions of the bad medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. Ball valve body can be whole, also can be combined.

Ball valve has been widely used in petroleum, chemical industry, power generation, paper making, atomic energy, aviation, the rockets and so on various sectors, as well as People's Daily life. Ball valve in the irrigation system is widely used in the, basically use in pipe inlet. Ball valve simple structure, small volume, to flow resistance is small, the disadvantage is open or closed too fast, can be in pipeline middle living water hammer (pipe speed suddenly change pressure increases). So in ZhuGanGuan on unfavorable use ball valve, can be used in in dry and pipe or its end at the use of cleaning, for washing drainage effect is good.
