SMART IN FLOW CONTROL

FROSTY – Type 3598 Cryogenic Valve for high-pressure applications

Developed to meet our customers' requirements

  • Minimized loss of energy to the atmosphere 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, optionally with a cover plate
  • Valve maintenance possible without removing it from the cold box or removing the insulation
  • The valve seat, piston and circulation inhibitor can be accessed after removing the actuator
  • Cv coefficients and valve characteristic can be adapted through the use of custom cages

Customer requirements Challenge Solution
High energy efficiency Large difference between operating temperature and ambient temperature Design ensures closure to the environment
Quick and easy in-line servicing Valve can be completely enclosed or insulated Top-entry design allows access to all parts subject to wear without removing the cold box or insulation
Very compact valve unit High actuator forces are required to handle high pressures The standard pressure balancing installed allows the use of compact, lightweight actuators
Severe service conditions, e.g. due to higher pressure drops, cavitation and flashing Control of severe service conditions, preventing vibrations, minimizing wear Rugged cage design
