Evolution of Ball Valve

Ball valve is evolved from the stopcock, it has the same rotation of 90 degrees to mention, but the cock body is a sphere, a circular through-hole or channel through its axis. Ratio of the sphere and the port should be such, when the ball is rotated 90 degrees, in the import and export should be rendered sphere fully, thus cutting off the flow.
Ball valve just use operation of the rotary 90-degree and a small torque to be closed tightly. Full equality body cavity provide a little resistance flow channel for the media. It is generally considered that ball valve is most suitable to open and close done directly, but recent development has been made it have throttle and control the flow. The main features of valve is its own compact, easy operation and maintenance for water, solvents, acids and gas and other general work media, but also applies to the poor working conditions of media, such as oxygen, hydrogen peroxide. Ball valve can be integral, it can also be modular.
