Fluid resistance is small, and its resistance coefficient is equal to the pipe segment of the same length. Simple structure, small volume, light weight. Tight and reliable, the sealing surface material of ball valve is widely used plastic, good tightness, and has been widely used in vacuum system.

High platform ball valve is a relatively new type of ball valve, it has some advantages unique to its own structure, such as frictionless switch, seal is not easy to wear, opening and closing moment is small. In this way, the specification of the actuator can be reduced. With multi - rotation electric actuator, the medium can be adjusted and cut off. Widely used in petroleum, chemical industry, urban water supply and drainage requirements of strict cut off conditions.
