Plug valve is a closed or plunger shaped rotary valve, by rotating 90 degrees to make the valve plug on the mouth of the channel and the valve body on the mouth of the same or separated, to achieve a valve opening or closing. The plug of the plug valve can be cylindrical or conical in shape. In the cylindrical valve plug, the channel is generally rectangular; and in the tapered valve plug, the channel is trapezoidal. These shapes make the structure of the stopcock lighter, but at the same time produce some losses. Plug valves are most suitable for cutting and closing media and for shunting applications, but according to the applicable nature and erosion resistance of the sealing surface, sometimes can also be used for throttling. Because of the wiping action between the sealing surface of the plug valve, it can completely prevent the contact with the flow medium when it is fully open, so it can also be used in the medium with suspended particles. Another important feature of the plug valve is that it is easy to adapt to the multi-channel structure, so that a valve can get two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valves used and some of the fittings required for the equipment.
Plug valve application:
Plug valves are widely used in oil production, transportation and refining equipment, but also widely used in petroleum, chemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC industry and general industry.
