Product details

First, thefloating 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 ¡ã 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.
