Fluorine Lined Flange Ball Valve

JOEPAI Fluorine Lined Flange Ball Valve is a corrosion-resistant shut-off valve widely used in the chemical, environmental protection, petrochemical, pharmaceutical, electroplating, and smelting industries. Adopting a full bore structure design and lined with PTFE, FEP or PFA material, it can efficiently block the corrosion of strong corrosive media on the valve body metal, and maintain long-term sealing and operation in extreme working conditions such as hydrofluoric acid, aqua regia, concentrated nitric acid, and strong alkali. The composite structure of the metal body and non-metallic anti-corrosion lining solves the common industry pain point of ordinary metal valves failing under corrosive conditions. The full bore design eliminates reduced-diameter dead zones, resulting in far lower fluid resistance than same-size globe valves and check valves, while the fully lined ball forms a precise sealing pair with the seat to achieve zero-leakage performance when closed. Manufactured using an integral compression lining process, the fluoroplastic lining is tightly bonded to the carbon steel valve body, preventing peeling or bulging even in long-term service. The low-friction inner lining also avoids medium clogging or jamming during operation, ensuring stable performance in applications that require extremely high levels of corrosion control.

Product Advantages
