The cryogenic ball valve is one of the important control components in the cryogenic ball valve pipeline system, especially suitable for the occasions requiring tight sealing, rapid opening and closing and low flow resistance. OUYI’s the cryogenic ball valve adopts the most advanced design concept and strictly controls the production process, which makes OUYI’s cryogenic ball valve have outstanding advantages such as reliable sealing, low operating torque, high low temperature stability and long service life. At present, OUYI’s cryogenic ball valve has been successfully used in many LNG receiving stations and liquefaction stations.
