2025 Top 10 Lined Ball Valves Suppliers in China

Introduction to Lined Ball Valves

Lined ball valves are a type of valve widely used in various industries. They consist of a ball with a hole in the middle that rotates to control the flow of fluid. The lining on the inner surface of the valve body and the ball provides protection against corrosion, abrasion, and chemical attack. This lining can be made of different materials such as PTFE (Polytetrafluoroethylene), PFA (Perfluoroalkoxy), and other fluoropolymers, depending on the specific application requirements. Lined ball valves are known for their excellent sealing performance, low operating torque, and long service life, making them suitable for handling corrosive and aggressive fluids in chemical, pharmaceutical, food and beverage, and other industries.
