Spherical body all welded structure valve body has low dead weight, and its ideal spherical body can cope with higher pressure and bending moment, and can withstand higher internal and external pressure. Different material combinations can be selected to ensure reliable operation of the valve in corrosive occasions, such as acid gas.

Spherical valve body assembly welding type: two longitudinal and two ring assembly welding type

The unique welding process is adopted to ensure the quality of multi pass welds and the deformation during welding. Special assembly process and tooling equipment to ensure assembly positioning accuracy.
