Descriptions Of Swing type Cryogenic Flange check Valve :
Specially designed check valves are required for cryogenic applications to meet operational requirements at temperatures significantly below freezing. Through specialized cryogenic treatment, rough-machined components are immersed in a cooling medium for several hours (2-8 hours) to relieve internal stresses and ensure optimal material performance under extreme cold conditions. These valves maintain functionality at temperatures as low as -196°C and are widely utilized across cryogenic industries including liquefied natural gas (LNG), liquefied petroleum gas (LPG), and air separation processes.
The closure element of a cryogenic flange check valve operates autonomously through medium flow and force to open or close, Prevent water backflow and reduce pipeline damage caused by water hammer .thereby preventing backflow Swing-type cryogenic flange check valves have unrestricted installation orientations and are typically deployed in horizontal pipelines, though vertical or inclined pipeline configurations are also feasible. Check valves exclusively permit unidirectional medium flow; the normal flow direction must align with the arrow indicator on the valve body to avoid interruption of regular medium circulation.
Instructions Of Swing type Cryogenic Flange check Valve :
01) Prior to connecting to the pipeline, it is imperative to thoroughly flush and remove any residual impurities within the conduit.
02) To ensure the proper functioning of the valve, it is advisable to install a filter at the pipeline inlet to prevent impurities from becoming lodged in the valve disc, which could compromise the valve's non-return performance.
