Wear Resistant Trunnion Type Ball Valve , Turbine A216 WCB Ball Valve
API Cast Steel Plange End 150 Class Trunnion Type Floating Ball Valve
Introduction
Worm gear flange ball valve and gate valve belong to the same type of valve. The difference is that its closing part is a sphere. The sphere rotates around the center line of the valve body to open and close. Ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline.
working principle
The valve is unblocked or blocked by rotating the valve. The ball valve has the advantages of light switch and small volume. It can be made into a large diameter, reliable sealing, simple structure and convenient maintenance. The sealing surface and spherical surface are often closed, which is not easy to be eroded by the medium. It has been widely used in various industries.
Worm gear flange ball valve is mainly used to cut off, distribute and change the flow direction of medium in the pipeline. Ball valve is a new type of valve widely used in recent years.
