The ball valve has the action of rotating 90 degrees, the cock body is a sphere, and a circular through hole or channel passes through its axis. The ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. It can be closed tightly only by rotating 90 degrees and a small rotating torque. Ball valve is most suitable to be used as switch and shut-off valve, but recent development has designed ball valve to throttle and control flow
Three way ball valves are T-shaped and L-shaped. T-shape can connect three orthogonal pipelines with each other and cut off the third channel, which plays the role of diversion and confluence. L-type can only connect two mutually orthogonal pipelines, and cannot maintain the interconnection of the third pipeline at the same time, which only plays a role of distribution
1. The three-way ball valve adopts the integrated structure in structure, the sealing type of four-sided valve seat, less flange connection, high reliability and lightweight design
2. The three-way ball valve is divided into T-type and L-type, with long service life, large circulation capacity and low resistance
3. The three-way ball valve is divided into two types: single acting and double acting. The single acting type is characterized by that once the power source fails, the ball valve will be in the state required by the control system
