Type 05415 - Check Valve
|
Cryogenic-Check Valves, PN50 Stainless steel body and bronze cap with spring, opening pressure ca. 0.1 bar "cleaned and degreased for oxygen service" Part No. 05415.X.0001 Female thread connection (G) acc. to ISO 228/1 Part No. 05415.X.0006 Female thread connection NPT acc. to ANSI B 1.20.1 Available options - on request only: - Female thread connection (R) acc. to ISO 7-Rc 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) |
