Determinants Of Corrosion Resistance Of 3-way Flanged Ball Valve

We all know that 3 Way Flanged Ball Valve are widely used in automatic control and remote control systems in industries such as food, environmental protection, light industry, petroleum, papermaking, chemicals, textiles, and power. They are relatively corrosion-resistant. So, what makes pneumatic fluorine-lined ball valves corrosion-resistant, and what are the key factors?

The materials used for the main components of pneumatic fluorine-lined ball valves are all relatively corrosion-resistant:

Valve body: cast iron, cast steel, stainless steel;
Valve core: stainless steel + polytetrafluoroethylene (F46);
Valve seat: polytetrafluoroethylene (F46);
Valve stem: 2Cr13;
Packing: flexible graphite, polytetrafluoroethylene;
Bracket: cast iron, cast steel, stainless steel;
Coupling: 25, 35, 45.

The inner cavity and body of pneumatic fluorine-lined ball valves are lined with 2.5-3mm thick F46, which is resistant to acids, alkalis, and strong corrosion. In general, the corrosion resistance of the pneumatic fluorine-lined ball valve depends primarily on the corrosion resistance of the materials used.
