Lined Ball Valves rely on elastomers (rubber) and/or polymers (PTFE) to totally isolate the valve body and stem journal area from the corrosive and/or erosive effects of the line media. When the body and stem journal area are isolated from the line media, the valve is regarded as a "non-wetted" design. By isolating the valve body and stem with rubber or PTFE, it is not essential for the valve body to be created of costly corrosion-resistant supplies like stainless steel, Alloy 20 and C-276.

When the valve body and journals are exposed to the line media like in gate valves, globe valves and lubricated Plug Valves, the valve is regarded as to have "wetted" parts.
