The pneumatic flanged ball valve is a ball valve coupled with a pneumatic actuator, which is relatively fast and does not require workers to work hand in hand, saving manpower and time to a large extent.
Pneumatic flange ball valve is evolved from the valve. It has the same rotation of 90 degrees to mention the action, the difference is that the plug body is a sphere, with a circular through hole or passage through its axis. The proportion of the spherical and the channel should be such that when the ball rotates 90 degrees, the entrance and exit should be spherical, so as to cut off the flow.
Pneumatic flange ball valve only need to rotate 90 degrees of operation and a small torque can be closed tightly. The fully equal body cavity provides a very small, straight passage for the medium. It is generally believed that the ball valve is most suitable for direct opening and closing use, but the recent development of the ball valve has been designed so that it has a throttle and control the flow of use. The main features of the ball valve itself is compact, easy to operate and repair, suitable for water, solvents, acids and natural gas and other general working medium, but also for poor working conditions such as oxygen, hydrogen peroxide, methane and ethylene. Ball valve body can be the whole, it can be modular.
