YDF fully welded ball valves are especially designed for gas transportation and storage industries. The fully welded body design can prevent any potential external leakage from connection of body and bonnet. 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.
