CRYOGENIC
Type 05419 - Check Valve, ASME B16.5 Flanges
|
Cryogenic-Check Valves, class 300 Stainless steel body and cap with spring, opening pressure ca. 0.1 bar "cleaned and degreased for oxygen service" Part No. 05419.X.0003 Flanged connection acc. to ASME B16.5 class 300 Check valves provide reliable backflow functionality when properly sized. Based on experience, the minimum operating range of the valve should be 50% for gases and 40% for liquids in relation to the total capacity of the valve. Lower flow rates can lead to unstable performance, excessive noise, and even component failure. Applications: Approved for air gases, vapours and cryogenic liquefied gases incl. LNG. Working temperature: -196°C / -321°F (77K) up to +120°C / +248°F (393K) |
