DN500 Welded Ball Valve is a large-diameter fully welded ball valve with an integrated structure design, directly connected to the pipeline through welding with no external leakage points. The product is suitable for large flow and medium-high pressure pipeline systems, widely used in large pipeline systems in industries such as oil, natural gas, chemical, and power as the main equipment for cutting off or connecting media. The DN500 welded ball valve features zero leakage, maintenance-free operation, and corrosion resistance, capable of stable operation in various harsh environments. The product is manufactured using high-quality materials and precision machining to ensure excellent sealing performance and operational flexibility even under large diameter conditions. The valve has a reasonable design with compact structure, making it an important component of modern large pipeline systems, especially suitable for critical applications with high sealing and reliability requirements.
