The pneumatic PTFE lined ball valve is a high-performance quarter-turn shut-off valve designed for reliable control of corrosive media. The inner surface of the valve body and all wetted components are lined using a high temperature molding fluoroplastic lining process, providing excellent corrosion resistance and long service life.
The lining materials include FEP (F46), PTFE, and PFA, which effectively isolate the process medium from the metal valve body. This structure prevents corrosion and ensures safe operation when handling aggressive chemicals.
The valve adopts a 90-degree rotary ball structure, allowing smooth operation, fast response, and excellent sealing performance. When used together with pneumatic actuators, solenoid valves, and control cabinets, it can achieve reliable on-off control in automated industrial systems.
This valve is widely used for controlling strong acids, alkalis, corrosive liquids, toxic gases, and volatile media in chemical, petrochemical, and environmental protection industries
