Type 05411 - Check Valve
|
Cryogenic-Check Valves, PN50 Bronze body and cap with spring, opening pressure ca. 0.1 bar "cleaned and degreased for oxygen service" Part No. 05411.X.0001 Male thread for union connection 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) |
