Ball valves is a quarter turn type valve, the colsure member is a ball which can rotating 90 °. When the valve is positioned where the bore is aligned in the same direction as the pipeline, the valve is open, and turning the ball by 90 °, then the valve closed. There’s a stem and trunnion to fix the ball, and the ball can not move like a floating ball valve, so called trunnion mounted ball valve. Compared with multi-turn valves, ball valves with shorter opening and closing time, longer lifetime, and less space for installation, and the opened or closed state of the valve can be easily detected by position of the handle. Ball valve is widely used in oil & gas, petrochemical, power industries, and usually for on-off application, not suitable for capicity control purpose.
