Cryogenic ball valves are used at extremely low temperatures, typically lower than -40℃ down to -196℃.
Cryogenic ball valves are mainly used for liquid media with low temperatures, like liquid oxygen, liquid hydrogen, liquefied natural gas and liquefied petroleum products and industrial gases. Such media are not only flammable and explosive, but will vaporise when heated so the volume expands rapidly during gasification.
Under extremely low temperatures and in the harshest of environments, Habonim’s series of cryogenic ball valves consistently exhibit high flow capacity, tight shutoff and long service-free life. Unmatched in reliability, stability and, most importantly, safety, Habonim’s cryogenic ball valves are used in air separation plants, industrial gases, LNG storage, distribution and transportation, and in the aerospace, petrochemical and medical industries.
