Ball valve from the plug valve. It has the same movement rotated 90 degrees to mention only difference is that cock body is a sphere, a circular through-hole or channel through its axis. The sphere and the ratio of openings should be such that when the ball rotated 90 degrees, in the import and export of office should be fully rendered sphere, thus cutting off the flow. Just use the rotary valve 90-degree rotation of the operation and a small torque can be closed tightly. The body cavity of full equality for the media to provide a little resistance, through the flow channel. Generally considered the most suitable valve opening and closing done directly used, but the recent development has been designed to give it a throttle valve and control the flow purposes. The main features of valve is its own compact, easy operation and maintenance for water, solvents, acids, and natural gas work in general media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene and so on. Ball valve can be integral, it can be modular.
