Plug Valves are part of the quarter-turn valve family and are named for their tapered end, which resembles a plug or cylinder. The disc acts as a bubble-tight shut-off and on mechanism, and the opening and closing mechanism is similar to that of a ball valve.
One of the primary advantages of plug valves is their simple mechanism, which makes them easy to use and maintain. In-line maintenance is also easy, and the valves have a low-pressure drop, making them highly efficient. They are also highly reliable and have a tight seal capability, which is essential in various industries. Additionally, they are fast-acting and only need a quarter turn to open or close.
Plug valves are highly effective as tight shut-off and on valves in many applications. They are commonly used in gas pipelines, slurries, and applications that contain high levels of debris, as well as in high-temperature and pressure applications. These valves are also great for sewage systems, and their design ensures that there is no contact between the media and the internal valve parts, making them ideal for highly abrasive and corrosive media.
