Fully Welded Ball Valves, also known as Welded Body Ball Valves, feature a fully welded body design. These valves are primarily used as stop/shutoff valves in water and gas supply systems, heat-power engineering, housing and communal services, as well as in process lines at chemical and oil-refining plants and pulp-and-paper production facilities. The forged materials undergo ultrasonic testing according to ASME nondestructive flaw detection standards, and the welding slope on the connection face is subjected to liquid penetration testing. A corrosion allowance is incorporated into the body wall thickness for added durability. The carbon steel stem, fixed shaft, ball, seat, and seat ring are chemically nickel-plated per ASTM B733 and B656 standards. Additionally, a range of corrosion-resistant materials is available for selection. For environments with sulfurization, valve materials can be chosen in accordance with NACE MR 0175/ISO 15156 or NACE MR 0103 standards, with rigorous quality control and inspection to ensure compliance with all relevant specifications and optimal service in harsh conditions.
