  • 3 way plug valve

    3 way plug valve

    3 way plug valve  is a closing piece or plunger shaped rotary valve, by rotating 90 degrees to make the port on the valve plug and the valve body of the same or separate, open or close a valve. The plug of a plug valve may be cylindrical or conical in shape. In cylindrical plugs, channels are generally rectangular; In the tapered plug, the channel is trapezoidal. These shapes make the structure of the plug valve lighter, but at the same time create a certain loss. The plug valve is most suitable for cutting and connecting medium and diversion, but depending on the nature of the application and the erosion resistance of the sealing surface, sometimes it can also be used for throttling. Because the movement between the sealing surface of the plug valve has a wiping effect, and when fully open, it can completely prevent contact with the flow medium, so it can also be used for medium with suspended particles. Another important feature of the plug valve is its ease of adapting to a multi-channel design, so that a valve can have two, three, or even four different flow channels. This simplifies piping design, reduces valve usage, and reduces the number of fittings needed in the equipment.
