Advantages of ball valves

1. the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.

2. simple structure, small size, light weight. 

3.reliable and reliable, ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.

4. easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. 

5. maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 

6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface. 

7.a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied. Ball valve has been widely used in petroleum, chemical, power generation, paper making, atomic energy, aviation, rocket and other departments, as well as people's daily life
