Three-piece forged steel ball valve and gate valve are the same type of valve. The difference is that the closing member is a sphere, and the ball rotates around the center line of the valve body to open and close a valve. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. The three-piece ball valve is a new type of valve that has been widely used in recent years, and the valve is generally installed horizontally.
