Our fully welded ball valves are especially designed for gas transportation and storage industries. The fully welded body design can prevent any potential external leakage path from connection of body and bonnet and making suitable for buried installation for gas transportation. In addition, the forged body with the advantages of consistent grain size and even thickness. Thus it inherently eliminates the conventional casted valve material defects, such as shrinkage, porosity.
The weight and overall dimensions are optimized by applying a shaped design and the fully welded ball valves are manufactured in a wide range of sizes and pressure classes from forgings.
