Introduction
A cryogenic check valve is designed to prevent backflow in cryogenic fluid environments such as LNG, liquid nitrogen (LN₂), and liquid oxygen (LO₂).
The disc automatically opens and closes according to flow direction, protecting piping systems and equipment from reverse flow while maintaining stable fluid movement.
Available in various types, including Swing Check, Lift Check, and SNDR.
