Description

The Cryogenic Check Valve plays a crucial role in cryogenic liquid storage and transportation systems by preventing the backflow of cryogenic media. When the medium flows in the designated direction, the valve flap opens under the medium’s force. Conversely, if there is backflow, the valve flap swiftly closes against the valve seat’s sealing surface due to its weight and the opposing force of the medium. This ensures effective prevention of medium backflow, characterized by flexible operation and reliable sealing.

Applicable Medium: Suitable for handling low-temperature media such as Methane, Liquid natural gas, Hexene, Carbon dioxide, Liquid ammonia, Liquid oxygen, Liquid nitrogen, Liquid hydrogen, and more.
