Description
A welded ball valve is a valve that is permanently connected to a piping system by welding. Its core opening and closing component is a sphere with a through-hole. Fluid flow is controlled by rotating the sphere 90 degrees. Because of its welded connection, it is considered a high-performance, permanent valve, particularly suitable for demanding applications requiring zero leakage and high safety.
