Cryogenic Valves
Cryogenic Check Valve
Extended-bonnet cryogenic check valves engineered for automatic backflow prevention in ultra-low temperature piping networks.
OVERVIEW
Reliable Cryogenic Flow Security
Our cryogenic check valves operate automatically to prevent backflow in lines carrying LNG, liquid nitrogen, oxygen, and other low-temperature media. Featuring an extended gas column bonnet to protect sealing integrity at temperatures down to -196°C, they deliver reliable, anti-slam, bubble-tight shutting under high-pressure process conditions.
