First, the worm floating ball valve Overview:
Ball valve is an important valve class, in the petrochemical industry, long-distance pipeline and other fields are widely used. The closing of the ball valve is a perforated sphere (or part of the ball), the ball with the stem rotation, to achieve the valve open or closed. 
In a variety of valves, the ball valve flow resistance is minimal, full diameter ball valve is opened, the ball channel, the valve body channel and connecting diameter equal to a diameter, the media can almost no loss of flow. 
Ball valve rotation 90 ° can be fully closed, open and close quickly. With the same specifications of the gate valve, compared to the valve, the ball valve small size, light weight, easy to pipe installation.
