Plug valve is a rotary valve with the plunger-shaped turned off piece, by rotating 90 °, the channel mouth stuffed with valves and valve openings is on the same or separate to achieve a valve open or closed. Valve plugs into a cylindrical or conical shapes. As the most appropriate for cutting off and connecting medium and shunting, the plug valve can sometimes be used for throttling according to the use of the nature and resistance to erosion of the sealing surface. As the campaign between the sealing surface has a polished function, when in the fully open, theplug valve can completely prevent contact with the flow medium, so it usually can also be used with suspended particles in the medium.
Plug Valve is widely used in oil extraction, transportation, and refining equipment, but also widely used in petrochemical, chemical, gas, natural gas, liquefied petroleum gas, HVAC industry, and general industries.
