Cryogenic Valves: Performance in Extreme Low Temperatures
Date:2025-03-15
Cryogenic valves are designed for liquefied gases such as LNG, liquid oxygen, and nitrogen. They function at temperatures as low as -196°C (-320°F) and require special materials to prevent brittleness.
Key Features:
-
Extended Bonnet Design: Prevents heat transfer and minimizes frost buildup.
-
Material Selection: Stainless steel, bronze, and monel for low-temperature durability.
-
Seat Design: Soft-seated options for tight shutoff and metal-seated for high-pressure cryogenic flow.
Applications:
-
LNG terminals and storage tanks.
-
Aerospace fuel systems (liquid oxygen valves).
Challenges:
-
Requires specialized testing, such as helium leak detection.
-
Higher operational costs due to material and design complexity.
