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.
