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.

Advantages and Applications of Metal Control Valves

As core final control elements in industrial automation systems, metal control valves utilize metal materials for critical components such as the valve body and sealing elements. They precisely regulate parameters such as fluid flow rate, pressure, and direction, making them widely suitable for demanding industrial conditions involving high temperatures, high pressures, and strong corrosiveness.
