The double seal plug valve has double blocking and discharge functions. The valve is equipped with a pressure balancing device to prevent abnormal pressure increase in the system and reduce the resistance at the moment of opening and closing of the valve. Because the metal surfaces of the sealing ring are in contact with each other after being compressed, the valve has a fireproof function. The maintenance of the valve is very convenient. The two side plates can be removed from the valve body and replaced by removing the end cap at the bottom of the valve body without disassembling the valve body from the pipeline. Therefore, it is also widely used in various industries such as petroleum, natural gas, metallurgical mining, gas engineering, light industry and textile, ship terminals, food and environmental protection water treatment for regulating, opening and closing pipeline fluids.
