First, the floating ball valve Overview:
Ball valve is an important valve in the petrochemical industry, long-distance pipelines and other fields have a wide range of applications. The closure of the ball valve is a ball with a hole (or part of the ball), the ball with the valve stem rotation, the valve to open or close. 
In a variety of valves, the ball valve flow resistance of the smallest, full-diameter ball valve opens, the ball channel, valve body and connecting pipe diameter equal to a diameter, the media can flow almost without loss. 
Turn the valve 90 ° to fully open all the way, opening and closing quickly. With the same specifications of the gate valve, globe valve comparison, small size ball valve, light weight, easy pipe installation.
