The manufacturing process of the cylindrical valve body structure is relatively simple, which is convenient for assembly and positioning. The mold required for blank manufacturing is simple, and it is convenient to use the support plate to fix the sphere.

Assembly and welding form of cylinder

Three bodies are welded by two symmetrical longitudinal welds or two bodies are welded by one longitudinal weld.

Features: The structure has good processability and is convenient for the installation of the valve stem. It is especially suitable for large diameter full welded ball valves. (Two bodies are applicable to small diameter all welded ball valves, and three bodies are applicable to large diameter all welded ball valves)
