CRYOGENIC VALVES AND EQUIPMENTS
The International Industrial Gases limited engineered seals capable of withstanding temperatures as low as -450º F. Configurations are low in mass to minimize thermal loss. Free standing and manifolds mounted versions are available.
CRYOGENIC VALVE   CRYOGENIC VALVE'S  DESIGN FEATURES

  • The valve has been designed so that moving parts which cone in contact with each other are made from different materials to prevent the mating surface from galling. This avoids any contamination of the service. 

  • P.T.E.F. is used as a sealing disk  within the loose valve to ensure tight shut off. 

  • A wafer thin fluorocarbon disk is located between the loose spindle end. This eliminates much of torque transmitted by the spindle at the point of closure resulting in positive seating of the sealing disk, without fear of scrubbing.
