Carbon Steel Fully Welded Ball Valve

The fully-welded ball valve adopts forged material, welded body, instead of bolts and nuts, to avoid any potential leakage from body. The forged body with regular structure and even thickness can avoid shrinkage cavities, pin holes, cracks, sand holes and other defects occurring to casting body valves. Fully-welded ball valves can be spherical and cylindrical type. Usually the spherical type has only one welding seam on the body, the cylindrical type has two welding seam on the body. Be able to be used for underground installation without corrosion of interior parts, therefore, it is the best application for petroleum and natural gas line systems.
