Type 05719 - Check Valve, DIN EN Flanges
|
Cryogenic-Check Valves, PN40 Stainless steel body and cap with spring, opening pressure ca. 0.1 bar "cleaned and degreased for oxygen service" Part No. 05719.X.0042 Flanged connection acc. to DIN EN 1092-1 PN40 Disc seal: PTFE / Carbon filled (25%) Part No. 05719.X.0052 Flanged connection acc. to DIN EN 1092-1 PN40 Disc seal: PTFE 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) |
