LQH's Cryogenic Check Valve is engineered for extreme low-temperature applications down to -196°C (-320°F), ensuring reliable backflow prevention in LNG, liquid oxygen, and nitrogen systems. Featuring stainless steel construction with PTFE seats, it maintains leak-proof performance under cryogenic conditions while minimizing pressure drop. The valve's robust design prevents freezing and ensures quick, automatic response to flow reversal, making it ideal for aerospace, energy, and laboratory applications where safety and efficiency are critical. With extended bonnet options and fire-safe certification, our cryogenic check valves deliver durable, maintenance-free operation in the most demanding industrial environments.
Specifically designed for LNG applications, our valves feature extended bonnets and special disc designs to handle cryogenic liquids safely while preventing backflow in storage tanks and transfer systems.
We offer both swing and lift check valve designs optimized for cryogenic service. Swing types provide low pressure drop while lift types offer precise sealing in vertical flow applications.
