Product Overview
In LNG and cryogenic liquid media systems, check valves need to maintain reliable operation and sealing performance under conditions of extremely low temperatures, frequent phase changes, and significant material shrinkage.
This is a 5mm cryogenic check valve designed for cryogenic applications, suitable for LNG and various cryogenic liquid media. It provides stable, backflow-preventing control at -196℃.
