Fluorine lined flange ball valve
The Fluorine Lined Flange Ball Valve is a high-performance corrosion-resistant valve designed for controlling highly corrosive, acidic, alkaline, and chemical media. The valve body and internal flow passages are fully lined with advanced fluorine materials such as PTFE (F4), PFA, FEP, or ETFE, providing outstanding chemical resistance, excellent sealing performance, and long-term operational reliability.
Fluorine lined flange ball valve
Featuring a full-port ball structure and flange connection design, this valve ensures low flow resistance, smooth operation, and reliable shut-off performance. The fluorine lining effectively protects the metal valve body from corrosion, making it suitable for demanding industrial applications involving aggressive fluids.
We offer professional OEM and ODM manufacturing services, supporting customized valve designs based on customer drawings, technical specifications, and application requirements. Customization options include valve size, pressure rating, flange standards, lining materials, actuator types, sealing structures, and special operating conditions. All products are manufactured under strict quality management systems with complete valve industry certifications and inspection documents, ensuring compliance with international market requirements.
