Introduction to the Classification of Fluorine-Lined Manual Valves

In highly corrosive operating environments, fluorine-lined manual valves are an essential choice. These industrial anti-corrosion valves are operated manually via a handwheel or handle, and all wetted parts—those that come into contact with the process fluid—are lined with fluoroplastics. Their primary advantage lies in combining the mechanical strength of a metal valve body with the exceptional corrosion resistance of fluoroplastics; they are specifically designed for the shut-off and basic flow regulation of highly corrosive media within pipelines.

Classification of Fluorine-Lined Control Valves

Fluorine-Lined Control Valves are essential components in industries such as chemical processing and oil & gas. In highly corrosive environments, valves lined with fluoropolymers prevent chemical damage to the valve’s internal body, ensuring proper operation.

Maintenance Guidelines for Fluorine-Lined Valves

Among anti-corrosion materials, polytetrafluoroethylene (PTFE) boasts unparalleled performance. With the exception of molten metals, elemental fluorine, and aromatic hydrocarbons, it resists corrosion from hydrochloric, sulfuric, and nitric acids (including aqua regia), organic acids, strong oxidizers, concentrated or dilute acids, alkaline solutions, and various organic solvents.
