Sleeved plug valves are non-lubricated quarter-turn valves that achieve sealing through the use of a compressible sleeve as a sealing member. In many applications they operate virtually maintenance free for decades.
Usually available in cylindrical or conical shapes, plug valves are quarter-turn manual motion valves used for stopping or starting the flow of fluid. They offer on-off, diverting, as well as basic moderate throttling services.
