The Cryogenic Top-Entry Ball Valve, as an important on/off component in the cryogenic pipeline system, is an important part of the petrochemical industry, air separation, and natural gas industry. The structure of Top-Entry Ball Valve can realize online maintenance, and is suitable for low-temperature liquid or gas media, such as liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid hydrogen, liquid oxygen, ethylene and other conditions. Compared with the Side-Entry ball valve under the same conditions, Top-Entry Ball Valve is more convenient to maintain with a wider scope of application, and is more common.
