■Summarize
Ball valve is an important valve. It is used in petrochemical, long transport pipeline and other scopes. It depends on a ball with a hole to open and close the valve.
In all the valves, ball valve’s flow resistance is the least. When opened the ball completely, the passages of ball and body are equal to the diameter of the pipe, so the medium can flow in the valve without any damnification.
It is convenient for open and close completely, if you turn the ball 90 degree. Compare with same specs gate valve and globe valve, the ball valve has such advantage as bellows: small volume, light weight and easy to install it with pipes.
