Special features

  • Minimized heat leak thanks to the use of a circulation inhibitor and a cryogenic extension bonnet
  • Installation in vacuum-insulated pipelines, air separation plants (cold box) and peripheral plants made possible by a cover plate on the cryogenic extension bonnet
  • Valve maintenance possible without removing it from the pipeline
  • Top entry through the cryogenic extension bonnet allows easy access to the seat, piston and circulation inhibitor after removal of the actuator
  • The Cv coefficients can be modified in wide ranges by replacing the seat and valve plug
  • Use of the valve in marine applications (e.g. on passenger ships, industrial tankers and offshore installations) possible
  • Developed to meet our customers' requirements
