Fully Welded Ball Valve, also known as the Welded Body Ball Valve, features a completely welded body for enhanced durability. These valves are designed for use as stop or shutoff valves in various systems, including water and gas supply, heat-power engineering, housing, communal services, as well as in chemical, oil-refining, and pulp-and-paper industries.
The forging materials undergo ultrasonic inspection per ASME nondestructive flaw detection standards. The connection face's welding slope is also tested with liquid penetration methods for quality assurance. The body wall thickness includes a corrosion allowance for added protection.
Key components such as the carbon steel stem, fixed shaft, ball, seat, and seat ring are chemically nickel-plated in accordance with ASTM B733 and B656. Additionally, a range of corrosion-resistant materials is available to suit specific needs. Valve materials can be selected according to NACE MR 0175/ISO 15156 or NACE MR 0103 standards to meet the requirements of sulfurizing environments. Strict quality control measures ensure that the valves meet industry standards and service conditions.
