What is the Main Difference
Fully Welded Ball Valve is a type of valve that has been designed with a welded body. Unlike other valves that have a body joint connecting the valve's body to the end connection, the Fully Welded Ball Valve has no such joint. This design reduces the valve's weight, enhances its serviceability, and makes it easy to handle. As a result, Fully Welded Ball Valves have become increasingly popular in various industries that require high-pressure and high-temperature applications. The valve is, therefore, an essential component in various plants.

What are the characteristics of ball valves?
Pneumatic ball valves have a simple and compact structure, reliable sealing, and easy maintenance. The sealing surface and spherical surface are often in a closed state, which is not easily eroded by the medium and is easy to operate and maintain. They are suitable for general working media such as water, solvents, acids, and natural gas. They are mainly used to cut off or connect media in pipelines, and can also be used for fluid regulation and control.

How does a ball valve work?
The working principle of a ball valve is to control the flow of fluid by rotating the ball. The main components of a ball valve include the ball body, valve seat, valve stem, and handle. When the handle rotates, the valve stem drives the ball to rotate, thereby changing the shape of the channel inside the valve body and achieving fluid on/off control.
