What is a Plug Valve?
On this page
The plug valve is a closing or plunger-shaped rotary valve, which opens or closes by rotating 90 degrees contributing the passage on the plug to be the same or separate from the passage on the body, realizing opening and closing of valve.
Its valve plug can be cylindrical or conical in shape. In a cylindrical valve plug, the passage is generally rectangular; in a tapered valve plug, the passage is trapezoidal. These shapes make the structure of plug valve become light. It is most suitable for use as a cutting and closing medium and a shunt, but it can also be used for throttling depending on the applicable property and the erosion resistance of the sealing surface.
