FULLY WELDED BALL VALVE
PRODUCT DESCRIPTION
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. The Full welded ball valve are mainly used in gas transmission and distribution pipeline, typically for underground and buried installation, this design is also used in many subsea application, where maintenance activities are not foreseen, the main advantage of this valve is that there is no leakage path through the joints. Forged steel body assures uniform the grain structure and toughness free from inevitable casting defects, such as porosity, abscess, sand hole, loosen, slag inclusion, crackle etc.
