A plug valve is a type of valve used to control the flow of fluids (liquids or gases) through a piping system. It consists of a cylindrical or tapered plug that can be rotated inside a hollow body to either block or allow fluid flow. The valve is named for its plug-like appearance and its function in plugging or sealing off the flow path.
