The valve can be field controlled by the indicator on an electric device, or remote controlled by a valve controller, or by program controlled by inputting signals into computer.

By the main air regulation and control of the high-temperature dust and gas or gas media containing high-temperature dust particles, the valve reaches the main purposes of cutting off, opening and closing, and adjusting pipeline media; Primarily used in blast furnace gas recovery and blast furnace hot air blowing system in the metallurgy industry, it is one of the key equipment for secondary use and control of large, extra large smelting blast furnace gas and high-temperature dust and gas.

Currently, the maximum diameter of the series extra-large high-temperature dust-gas butterfly valves is DN4850.
