The Hobbs Cryogenic Valve
(-196°C)

 

Features and Benefits

 

  • The zero leakage performance by means of its unique sealing principle and our triple off set concept allow full isolation to be maintained at cryogenic.
  • Given that the Hobbs Cryogenic valve does not have open cavities; fluids are unable to remain trapped after the valve is operated.
  • The metal to metal sealing is virtually unaffected by very low temperatures; the valve performance and the operating torque are identical at ambient and cryogenic temperatures.
  • The Hobbs one piece Shaft design ensures there is no potential of Stem failure.
  • Extended Bonnet comprising of an adequate gas column to keep the Shaft (Stem) packing away from cryogenic fluids. Generally supplied in a fabricated or cast condition with a minimum length of 250mm, Hobbs design capabilities allows us to provide solutions to your specific needs.
  • The quarter turn operation provides lower fugitive emissions than that of rising or multi-turn type valves.
  • The Extension Bonnet is connected to the valve by an ANSI standard flange connection.
