A ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, paper-making, pharmaceutical, water conservancy, electric power, steel and other industries, and plays an important role in economy.
The ball valve in the pipeline is mainly used to cut off, distribute and change the flow direction of the medium. It only needs to rotate 90 degrees with small torque to close tightly. It is opened when the hole of the ball is in line with the flow and closed when it is pivoted 90-degrees.
According to structure, a ball valve can be classified into three classes: floating ball valves, trunnion mounted ball valves, multi way ball valves.
According to connections, the ball valve can fall into flanged ball valves, fully welded ball valves and socket welded ball valves, ring type jointed (RTJ) ball valves.
According to materials used for the body, a ball valve can be divided into casting ball valves, forged ball valves, stainless steel ball valves, etc. According to materials used for the seat, the ball valve can be classified into soft seated ball valves and metal seated ball valves.
According to function, a ball valve falls into single ball valves, DBB ball valves and monoflange ball valves.
