DN1000 Welded Ball Valve is a large-diameter fully welded ball valve with an integral structure design, with no external connections on the valve body, completely connected to the pipeline through welding. The product has advantages of zero leakage, maintenance-free operation, and long service life, especially suitable for large-diameter, high-pressure, and hazardous medium pipeline systems. The DN1000 welded ball valve is widely used in important applications such as natural gas pipelines, oil pipelines, city gas networks, and chemical plants as the main equipment for cutting off or connecting pipeline media. The ball is manufactured using high-strength materials with excellent sealing performance and durability, making it a key equipment in modern pipeline systems.
