Worm gear fully welded ball valve

Overview：

Worm gear fully welded ball valve is a type of fully welded ball valve driven by worm gear transmission device. The valve body adopts integral welding technology (such as butt welding or socket welding), without flange connection, strong sealing, and avoids the risk of leakage. It is suitable for high-pressure, highly corrosive or buried harsh working conditions. The sphere is usually a solid or hollow structure, with a metal hard seal or soft seal (such as polytetrafluoroethylene, nylon, etc.) used for the sealing surface. It is paired with a valve seat to achieve bidirectional sealing, meeting the needs of cutting off or adjusting the medium. Worm gear fully welded ball valves, with their high sealing performance, high strength, and reliable transmission performance, have become the core cutting equipment for long-distance pipelines and high-pressure working conditions, especially playing a key role in the field of energy transmission.
