Feature
Made from materials that can withstand extremely low temperatures without becoming brittle or losing their strength. Common materials include stainless steel, Inconel, and other cryogenic-compatible alloys.
Cryogenic ball valves typically have an extended stem, which positions the actuator or handwheel away from the cold media. This design helps prevent frosting and allows for easier operation and maintenance.
Equipped with specialized seals and gaskets that maintain their integrity and flexibility at cryogenic temperatures, ensuring a tight seal to prevent leakage.
Designed with pressure relief features to safely vent any pressure buildup in the valve cavity caused by thermal expansion of trapped cryogenic fluids.
Some cryogenic ball valves offer double block and bleed functionality, allowing for isolation of the pipeline and venting of any trapped cryogenic fluid, enhancing safety during maintenance.
Many cryogenic ball valves are designed to be fire-safe, ensuring that they maintain their sealing capability even in the event of a fire.
Incorporates anti-static devices to prevent the buildup of static electricity, which is crucial in preventing sparks that could ignite flammable cryogenic gases.
Designed to meet stringent emissions standards, minimizing the release of volatile organic compounds (VOCs) and other harmful emissions.
Engineered to provide high flow rates with minimal pressure drop, ensuring efficient handling of cryogenic fluids.
Features to minimize thermal conduction from the cryogenic fluid to the valve body and actuator, reducing the risk of freezing and ensuring reliable operation.
Available in both trunnion mounted and floating ball designs, depending on the specific application requirements and size of the valve.
Built to withstand the harsh conditions of cryogenic service, offering long service life and reliable performance under extreme temperatures.
Application
Used in LNG production, storage, transportation, and regasification processes to control the flow of liquefied natural gas at temperatures around -162°C (-260°F).
Employed in handling liquefied petroleum gas, which requires valves that can operate reliably at low temperatures.
Installed in storage tanks for cryogenic fluids like liquid nitrogen, liquid oxygen, liquid argon, and other industrial gases, ensuring safe and efficient flow control.
Used in air separation units (ASUs) to control the flow of cryogenically separated gases such as oxygen, nitrogen, and argon.
Applied in processes involving the handling and storage of cryogenic chemicals and petrochemical products.
Utilized in rocket propulsion systems and ground support equipment for controlling cryogenic propellants like liquid hydrogen and liquid oxygen.
Used in the storage and transport of cryogenic medical gases such as liquid oxygen and liquid nitrogen for medical and pharmaceutical applications, including cryopreservation.
Employed in processes that require cryogenic freezing, such as the freezing of food products using liquid nitrogen.
Used in processes involving cryogenic treatment of metals to improve their properties or in the handling of cryogenic coolants.
Utilized in the cooling and cryogenic treatment of electronic components and semiconductor materials.
Essential in scientific research facilities and laboratories that conduct experiments involving cryogenic fluids.
Used in hydrogen energy systems, including hydrogen production, storage, and fueling stations where liquid hydrogen needs to be controlled.
Installed in transport vessels, pipelines, and distribution systems for cryogenic liquids to ensure safe and reliable flow control.

Frequently Asked Questions
Q: What is the primary design standard for this floating ball valve?
A: The valve is designed according to the API6D standard, with face-to-face dimensions conforming to ASME B16.10 and flange dimensions complying with ASME B16.5.
Q: What material is used for the body of this valve?
A: The body material is C95800, which is a high-strength aluminum bronze alloy that offers excellent resistance to corrosion, particularly in seawater and marine environments.
Q: Why do cryogenic ball valves require an extended stem design?
A: The extended stem positions the actuator or lever away from the extremely cold media. This prevents frosting, protects the stem packing from freezing, and ensures safe and smooth operation.
Q: What testing standards are applied to ensure pressure and dimension accuracy?
A: The valves undergo strict pressure testing in accordance with the API598 standard, alongside comprehensive dimensional inspections to ensure compliance with technical drawings.
Q: What is the medium application (W.O.G) for this valve?
A: W.O.G stands for Water, Oil, and Gas. This valve is engineered to control and isolate the flow of these media safely under specified temperature and pressure ratings.
