Dafram Cryogenic Ball Valves
DAFRAM ball valves for cryogenic applications are available in floating or trunnion mounted ball and in side-entry or top-entry body design. Seat design and gasket materials are designed and selected in order to meet the most demanding requirements of leak rate and fugitive emission. New valve design and components are validated by R&D Department.
Helium and Nitrogen cryogenic tests are performed internally in special test rigs boxes for valves up to 36” size.
