Cryogenic globe valves are specifically designed to operate at extremely low temperatures, typically ranging from -50 C to -273°C. They are used in various applications where maintaining the integrity of the flow at such low temperatures is crucial. Here are some common applications:
Liquefied Natural Gas (LNG) Industry: These valves are essential in LNG production, storage, and transportation facilities to control the flow of liquefied gases.
Industrial Gas Production: They are used in the production and handling of industrial gases like liquid oxygen, nitrogen, and helium.
Aerospace: Cryogenic globe valves are employed in aerospace applications, including rocket propulsion systems, where they manage the flow of cryogenic fuels.
Medical and Research Facilities: These valves are used in facilities that handle cryogenic liquids for medical purposes, such as MRI machines, and in research applications like superconductivity and particle accelerators.
Nuclear and Fusion Energy: They are also used in nuclear power plants and experimental fusion reactors to control cryogenic fluids.
Cryogenic globe valves are chosen for these applications due to their ability to provide a tight seal and reliable operation under extreme conditions. Some of the Special features:
- The extended bonnet feature of these valves locates the packing away from the cold media in the valve to prevent the damage of the stuffing box.
- Cavity relief in order to protect the valve body against overpressure caused by thermal expansion / liquid evaporation.
- Insulation collar / Drip plate / Insulation ring is a circular plate welded to the valve bonnet extension in order both to identify extent of the insulation and to avoid condensation entering the insulated area.
