Cryogenic globe valve belongs to the category of low-temperature valves, with a service temperature range of -196°C to 150°C. It is primarily used in low-temperature medium delivery systems such as liquefied natural gas (LNG), liquid oxygen, and liquid nitrogen, as well as in high-temperature and high-pressure pipelines in thermal power plants and nuclear power stations.

Advantages of Cryogenic Globe Valves
Simple structure, making manufacturing and maintenance relatively convenient.
Short operating stroke, enabling quick opening and closing.
Good sealing performance, with minimal friction between sealing surfaces, resulting in a longer service life.
Disadvantages of Cryogenic Globe Valves
High fluid resistance, requiring greater force for opening and closing.
Unsuitable for media containing particles, high viscosity, or prone to coking.
Poor flow regulation capability.
