ITT Habonim Cryogenic DC47 Diverter Valves UK & Ireland

ITT Habonim Cryogenic DC47 Diverter Valves

ITT Habonim’s DC47 cryogenic valves have numerous flow combinations. They enable the piping designer to save valves, space and flow elements while enhancing safety and simplicity. The diverter valve can save 2-3 valves, and facilitate the safe and easy changeover of cryogenic fluids.

Under extremely low temperatures and in the harshest of environments, ITT Habonim’s 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 valves and used in air separation plants, industrial gases, LNG storage, distribution and transportation, and in the aerospace, petrochemical and medical industries.
