Description:      

The LNG top entry ultra-low temperature ball valve is a very common on-off valve in the transportation of LNG and some cryogenic media. It is an important part of the petrochemical industry, air separation, and energy transportation industry. The top entry ultra-low temperature ball valve adopts a top-mounted fixed valve body with an extension stem in the middle. The internal part can be divided into metal seal and soft seal, and is subjected to repeated cryogenic treatment to ensure low-temperature resistance. The LNG top enrty ultra-low temperature ball valve is suitable for low temperature (-196℃~-100℃) liquid or gas, such as liquefied LNG, LPG, CNG, liquid hydrogen, liquid oxygen, ethylene, etc.
