Type 05414 - Check Valve
|
Cryogenic-Check Valves Stainless steel body and cap with spring, opening pressure ca. 0.1 bar Part No. 05414.X.0051, PN25 Butt weld connection for stainless steel pipes acc. to ISO 1127 or ASTM A312 Part No. 05414.X.0054, PN25 Socket weld connection for stainless steel pipes acc. to ISO 1127 or ASTM A312 Available options - on request only 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 hydrogen, air gases, vapours and cryogenic liquefied gases incl. LNG. Working temperature: -255°C / -427°F (18K) up to +120°C / +248°F (393K) |
