Plug valves are shutoff or plunger shaped rotary valves that open or close a valve by rotating 90 degrees so that the port on the plug is identical to or separate from the port on the body.The plug of the cock valve can be cylindrical or conical in shape.In a cylindrical plug, the passage is generally rectangular;In the conical plug, the channel is trapezoidal.These shapes make the design of the plug valve light, but at the same time cause some loss.Plug valves are best suited for cutting and connecting media as well as for shunt applications, but may also be used for throttling, depending on the nature of application and the erosion resistance of the sealing surface.As a result of the plug valve between the movement of the sealing surface with wiping effect, and in full open can completely prevent contact with the flow of media, so it is usually used with suspended particles of the medium.Another important feature of plug valves is their ability to adapt to a multi-channel structure so that one valve can have two, three, or even four different flow channels.This simplifies the design of the piping system and reduces the number of valves and connections required in the equipment.
