PFA lined plug valve is a plug valve that has a polymer coated on the inside of the valve body and other components. The valve has a body which contains the plug, a plug seat and the stem that erects to the outside of the body to connect with the handle. The ptfe sleeved plug valve has the sleeve covered with PTFE and the valve operates by the raising and lowering of the plug. The plug can be made up of different material types. The valve body is different than the inner components. When the stem is lowered, the plug is lowered into the hole in the plug seat.

pfa coated Awwa C517 Plug Valve
This closes the valve. When the stem is raised, the plug move away from the seat and the hole opens opening the valve. The ptfe lined valves are used in water, acidic, caustic and other corrosive solutions as well due to the anticorrosive PFA coating inside. The valves can come in different dimensions and pressure classes as well.
The Ptfe Plug Valves is made up of ductile iron, cast iron, carbon steel, stainless steel and other material grades based on the required levels of corrosion resistance, temperature resistance and the pressure capacities. The pfa lined plug valves can come in diameters ranging from ½ inches through 24 inches in general. The valves however can be made in larger dimensions based on the application requirements.
