Plug valves control flow using a cylindrical or tapered plug with a passage. They provide quick on-off operation with a quarter turn. These valves are known for tight sealing and leak-proof performance. Plug valves are suitable for handling slurries, viscous fluids, and corrosive media. Their simple design ensures easy operation and maintenance. They are commonly used in chemical processing and oil industries. Plug valves offer low flow resistance when fully open. Their durability makes them suitable for demanding industrial conditions.
