PTFE lined ball valve is a type of ball valve that has the ptfe coating. The ptfe is synthetic material known as polytetrafluoroethylene. The material prevents the core material from corroding under corrosive media. The ball valves come in different types as well. The pfa lined ball valve comes in carbon steel 1.0446, stainless steel 316, ductile iron GGG35.3 and other material grades as well. The disc material also varies as stainless steel, ductile iron and other material types. The O-ring comes in branded types. The pfa lined ball check valve also has different dimensions according the different standards. The nominal width ranges from DN50 through DN600. The operating pressure of the valves is PN10.

There are higher pressure capacity valves for high pressure applications as well. The operating temperature ranges from -20 degrees to 200 degrees Celsius. The connection type is lug or wafer depending on the connected pipes and the material flowing through the valves.
The face to face type of the 3 way ball valve ptfe lined can be ASME B16.10 or other internationally recognized standards and the design and manufacturing types have standards as well. The manufacturing design varies as API 609, DIN EN 1092 and so on. The ptfe lined ball check valve also comes with ASME B16.14 as the pressure and temperature standard. The spark testing is done at 14kv voltage. The applications of the valves include water, oil, petroleum and other industrial applications.
