Product Introduction
A Fully Welded Ball Valve is a high-integrity isolation valve designed with a body that is welded into a single piece—no flange-bolted body joints—ensuring outstanding leak tightness, structural integrity, and durability. It is especially suitable for high-demand applications such as pipelines, buried service, or where external leakage must be minimized.
