Plug valves are effective tight shut-off and on valve. There are many applications that use plug valves. These include gas pipelines, slurries, applications that contain high levels of debris, as well as high temperature and pressure applications. These valves are great for sewage systems. Since there is no contact between the media and the internal valve parts, plug valves are also great for highly abrasive and corrosive media.
