DN1600 Welded Ball Valve is one of the largest diameter fully welded ball valves currently available, specially designed for ultra-large flow and high-pressure pipeline systems. The product employs advanced manufacturing processes and strict quality control to ensure excellent performance even under ultra-large diameter conditions. The DN1600 welded ball valve is widely used in major national engineering projects such as the West-to-East Gas Pipeline, large-scale LNG terminals, transnational oil and gas pipelines, etc., serving as a key equipment for ensuring safe energy transmission. The product features zero leakage, maintenance-free operation, and long life, capable of withstanding extreme operating conditions including extremely low temperatures, extremely high pressures, and corrosive media. The ball and seat are made of special materials with surface treatment technology to ensure excellent sealing performance even under ultra-large diameter conditions.
