Feature
1. Material Selection
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.
2. Extended Stem Design
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.
3. Low Temperature Sealing
Equipped with specialized seals and gaskets that maintain their integrity and flexibility at cryogenic temperatures, ensuring a tight seal to prevent leakage.
4. Cavity Pressure Relief
Designed with pressure relief features to safely vent any pressure buildup in the valve cavity caused by thermal expansion of trapped cryogenic fluids.
5. Double Block and Bleed Capability
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.
6. Fire-Safe Design
Many cryogenic ball valves are designed to be fire-safe, ensuring that they maintain their sealing capability even in the event of a fire.
7. Anti-Static Device
Incorporates anti-static devices to prevent the buildup of static electricity, which is crucial in preventing sparks that could ignite flammable cryogenic gases.
8. Low Emissions
Designed to meet stringent emissions standards, minimizing the release of volatile organic compounds (VOCs) and other harmful emissions.
9. High Flow Capacity
Engineered to provide high flow rates with minimal pressure drop, ensuring efficient handling of cryogenic fluids.
10. Thermal Conduction Protection
Features to minimize thermal conduction from the cryogenic fluid to the valve body and actuator, reducing the risk of freezing and ensuring reliable operation.
11. Trunnion or Floating Ball Design
Available in both trunnion mounted and floating ball designs, depending on the specific application requirements and size of the valve.
12. Reliability and Durability
Built to withstand the harsh conditions of cryogenic service, offering long service life and reliable performance under extreme temperatures.
These features make cryogenic ball valves essential components in industries where handling extremely low-temperature fluids is necessary. Their design ensures safety, reliability, and efficiency in challenging cryogenic environments.

Frequently Asked Questions
What are the main standards followed by this Floating Ball Valve?
This floating ball valve complies with API6D for design, ASME B16.10 for face-to-face (FTF) dimensions, ASME B16.5 for flange dimensions, and API598 for pressure testing standards.
Why is the C95800 material chosen for the valve body?
C95800 is a high-strength aluminum bronze alloy known for its excellent resistance to corrosion, particularly in seawater and marine environments, making it highly durable for W.O.G (Water, Oil, Gas) applications.
What is the benefit of the extended stem design in cryogenic ball valves?
The extended stem design positions the actuator or handwheel far enough away from the cold cryogenic media to prevent frosting, which protects the actuator and allows for safe, easy operation and routine maintenance.
How does the valve handle cavity pressure buildup?
Cryogenic ball valves feature a specialized cavity pressure relief design. This safely vents any unexpected pressure buildup in the valve cavity caused by the rapid thermal expansion of trapped cryogenic fluids.
What applications are suitable for this floating ball valve?
It is ideal for W.O.G (Water, Oil, Gas) media. Additionally, cryogenic ball valves are widely used in LNG industries, cryogenic storage tanks, air separation plants, chemical processes, and aerospace propellant systems.
