Cryogenic Valves

Cryogenic Valves – Precision Control for Ultra-Low Temperature Systems

Cryogenic valves are specialized components engineered to operate reliably in extremely low-temperature environments, typically below -100°C. These valves are essential for safely managing the flow of cryogenic fluids such as liquefied natural gas (LNG), liquid oxygen (LOX), liquid nitrogen (LN2), liquid hydrogen (LH2), and liquid helium. Their primary function is to ensure secure containment and precise control of these volatile substances during storage, transportation, and processing. 

Key Features

• Extended Bonnet Design: Prevents heat transfer to the valve stem and packing, maintaining a reliable seal and preventing thermal expansion issues.

• High-Performance Materials: Constructed from materials like stainless steel, brass, and specialized alloys that retain mechanical properties at cryogenic temperatures, ensuring durability and resistance to embrittlement.

• Leak-Tight Seals: Equipped with metal-to-metal seats and seals designed to withstand extreme cold, providing bubble-tight shutoff to prevent leaks. 

• Pressure-Responsive Operation: Designed to open under high pressure, allowing controlled flow of cryogenic fluids, and to close securely when pressure decreases, ensuring system integrity. 

Applications

• LNG and CNG Systems: Critical for regulating the flow of liquefied natural gas and compressed natural gas in storage and transportation pipelines. 

• Aerospace Propulsion: Used in rocket propulsion systems to manage the flow of liquid hydrogen and oxygen, essential for space missions. 

• Medical and Pharmaceutical: Facilitate the safe handling of medical gases like liquid oxygen and nitrogen, used in therapies and cryopreservation. 

• Industrial Gas Production: Control the flow during the liquefaction and separation of air into components such as nitrogen and argon in air separation units.
