Flange Plug Valve Sizes - 2" through 24" A plug valve is a quarter turn valve that has a conical or cylindrical plug that is rotated within the valve body to stop flow when needed.  Plug valves function similar to a ball valve where the plug has an opening in the plug that allows fluid to flow through the valve when it is open.
