This kind of valve derives its name from the rotating plug which forms the closing element.The plug may be cylindrical or truncated. In the open position, the fluid flows through a hole in the plug.Lubricated plug valves rely on a sealing compound injected between the plug and the valve body, whilst sleeved plug valves are fitted with a "soft" insert between the plug and the body.
