Fluorine lined gate valve
The Fluorine Lined Gate Valve is a high-performance corrosion-resistant shut-off valve designed for reliable isolation of highly corrosive fluids in demanding industrial environments. The valve body and wetted components are lined with advanced fluorine materials such as PTFE, FEP, PFA, or ETFE, providing outstanding resistance to strong acids, alkalis, solvents, and other aggressive chemical media.
Fluorine lined gate valve
Featuring a gate structure, this valve provides full flow passage, low pressure drop, excellent sealing performance, and reliable shut-off capability. The fluorine lining completely separates the metal valve body from the process medium, effectively preventing corrosion and extending service life under severe operating conditions.
The valve is suitable for pipelines requiring frequent corrosion protection and dependable isolation. It can be operated manually or equipped with pneumatic/electric actuators for automated industrial systems.
We offer professional OEM and ODM customization services, including customized valve dimensions, pressure ratings, fluorine lining materials, connection standards, actuator configurations, sealing solutions, logo branding, and packaging requirements. Our engineering team can provide customized solutions based on customer drawings, technical specifications, and special working conditions.
Our fluorine lined gate valves are manufactured under strict quality management systems and supplied with complete valve industry certifications and inspection documents, including ISO quality certification, CE certification, material certificates, pressure test reports, and other internationally recognized valve industry certificates, ensuring reliable quality and compliance with global standards.
