A fully welded ball valve features a full-welded structure, with its core characteristic being the welding of all parts of the valve body to eliminate the risk of leakage that may exist with traditional flange or threaded connections. Simultaneously, it controls the flow of the medium through the rotation of the ball.

Structural Features

‌Full-welded design: The valve body, valve stem, sealing ring, and other components are all connected by welding, without bolts or flange structures, fundamentally eliminating the risk of leakage.‌

‌Welding Process: The butt welding method ensures complete isolation between the sealing surface and the medium, reducing the risk of erosion to the sealing surface by the medium.‌

Sealing Materials: Commonly used combination of PTFE carbonized sealing rings and disc springs, adaptable to pressure and temperature variations, ensuring sealing reliability.

Function Advantages

‌Sealing Performance: The fully welded structure eliminates leakage points at traditional joints, significantly enhancing sealing performance.‌

‌Easy Maintenance: Simplified structure reduces maintenance costs and makes seal replacement convenient.‌

‌Application Range: Suitable for high-pressure, high-temperature, or corrosive medium environments; applicable to pipe diameters ranging from a few millimeters to several meters.‌

This valve combines the dual advantages of fusion welding technology and a full-welded structure, ensuring both sealing reliability and simplifying the installation and maintenance process, making it suitable for various industrial pipeline applications.
