The plug valve is a kind of valve which uses the plug with a through-hole as the opening and closing part. The plug rotates with the valve stem to realize the start and closing action. The plug of the plug valve is mostly a cone (also cylinder). The sealing pair is matched with the conical hole surface of the valve body.
The plug valve is one of the earliest used valves. It has the advantages of simple structure, small size, fast opening and closing, and low fluid flow resistance, but it isn't easy to process and maintain. The standard plug valve is sealed by the direct contact between the dead metal plug body and the valve body, so the sealing performance is poor. The opening and closing forces are significant. It needs a sizeable rotating torque and is easy to wear.
