Detail Information
Fully Welded Body Ball Valve
Ball valves with a fully welded body are designed to minimize leakage points, significantly reducing maintenance requirements and ensuring a stable pipeline operation.
They are particularly valuable in scenarios where avoiding atmospheric leakage is crucial, such as in gas transmission pipelines. Available in both three-piece and two-piece fully welded constructions, these valves offer robust performance and enhanced safety in critical applications. These valves are ideal for applications in Oil & Gas production, processing, transportation, distribution, as well as chemical and petrochemical refining, both above and below ground.
We manufactures the following ball valves
