What is a Fully Welded Ball Valve?
A fully welded ball valve is a valve type where the body and components are welded together without bolts, preventing external leaks and enhancing structural integrity. This design is essential for high-pressure, high-temperature, and corrosive applications, including subsea, offshore, and chemical processing industries. These valves are favored for their durability, safety, and minimal maintenance requirements.
The welded construction eliminates potential leak paths that exist in valve designs with bolted joints. By fully welding the body, manufacturers ensure a hermetically sealed valve preventing fluid or gas from escaping into the environment. This feature is especially important in industries where leak prevention is critical for environmental and operational safety, such as oil and gas or chemical plants. Moreover, fully welded ball valves generally provide enhanced pressure ratings due to the robust nature of welding compared to bolting.
