Description
The Cryogenic Top-Entry Ball Valve serves as a crucial on/off component within cryogenic pipeline systems, playing a vital role in industries such as petrochemicals, air separation, and natural gas. Its innovative top-entry structure allows for convenient online maintenance, making it ideal for handling low-temperature liquid or gas media such as liquefied natural gas (LNG), liquefied petroleum gas (LPG), liquid hydrogen, liquid oxygen, and ethylene. Compared to side-entry ball valves, the top-entry design offers broader applicability and easier maintenance under similar conditions.
