Q341F Type worm gear floating ball valve Overview:
The ball valve is a valve, is important in the petrochemical industry, pipelines, etc are widely used. Ball valve fitting is closed with a hole in the ball (or part of the ball), spheroid rotation, open or close the valve.
In all kinds of valves, valve's flow of least resistance, the whole track ball valve is open, the sphere of the channel, the channel and connection valve diameter equal to the diameter of a free media is almost lost.
Ball rotation 90° To close all open, and close rapidly. And the same specifications comparison gate valve, globe valve, ball valve of small volume, light weight, convenient for pipeline installation.
