Background

The plug valve is a valve which is a closing member or a plunger-shaped rotary valve and is opened or closed by rotating 90 degrees to enable a passage opening on the valve plug to be communicated with or separated from a passage opening on the valve body. Its valve plug may be cylindrical or conical in shape. In a cylindrical valve plug, the passageway is generally rectangular; whereas in a conical valve plug the channel is trapezoidal. These shapes make the structure of the plug valve light. Most suitable for use as a shut-off and shut-on medium and shunt, but may sometimes be used for throttling depending on the nature of the application and erosion resistance of the sealing surfaces. The top drive manual plug valve is one of the plug valves.
