Fully Welded Ball Valve, also known as Welded Body Ball Valve, is designed with a fully welded body, making it a reliable solution for various industrial applications. These valves are ideal for use 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, oil-refining, and pulp-and-paper production facilities. The valve body undergoes rigorous testing, including ultrasonic examination according to ASME nondestructive flaw detection standards, and liquid penetration testing on the welding slope of the connection face. To ensure durability, the carbon steel stem, fixed shaft, ball, seat, and seat ring are chemically nickel-plated according to ASTM B733 and B656. Additionally, various corrosion-resistant materials are available to meet specific customer needs. The valve materials can be selected per NACE MR 0175/ISO 15156 or NACE MR 0103 for service in sulfurizing environments, with stringent quality control procedures during manufacturing to meet these standards.
