Low temperature ball valve

Product Overview:

The Low Temperature Ball Valve is specifically designed for use in applications involving extremely low-temperature environments, such as cryogenic systems. These valves are built to provide reliable shut-off, control, and isolation for fluid flow at temperatures down to -196°C (the temperature of liquid nitrogen). Made from specialized materials, they are engineered to withstand the physical stresses and performance demands posed by cryogenic and low-temperature applications.

Low Temperature Ball Valves are often employed in industries like liquefied natural gas (LNG) transport and storage, cryogenic research, and industrial gas applications. Their ability to maintain functionality at sub-zero temperatures makes them crucial for the safe and efficient handling of fluids like natural gas, liquefied gases, and other low-temperature media.

Key Features:

Cryogenic Performance: Specifically designed to operate efficiently in cryogenic conditions, ensuring tight sealing and reliable performance at temperatures as low as -196°C.

Specialized Materials: The valve body and other critical components are made from materials such as stainless steel, carbon steel, and alloy steels with low-temperature-resistant properties, such as 304L, 316L, or LCB, to maintain strength and durability under freezing conditions.

Bubble-tight Sealing: The low temperature design ensures the ball valve provides bubble-tight shut-off even under extreme cold conditions, reducing the risk of leaks and ensuring the integrity of the system.

Low Friction Operation: The valve’s ball and seat are designed for low-friction operation, ensuring smooth opening and closing actions without the risk of freezing or jamming, common in low-temperature applications.

Fire-safe Design: Often equipped with fire-safe seals and features, ensuring that even in the event of a fire, the valve will continue to provide a reliable seal to prevent leakage.

Full Port Design: Most low-temperature ball valves come with a full port design, which provides an unobstructed flow path, minimizing flow resistance and pressure drop, making them ideal for high-flow applications.

Extended Stem: To ensure the valve can be operated remotely in cryogenic environments, many low-temperature ball valves come with an extended stem, which isolates the operator from the freezing conditions.

Advantages

Reliable Performance in Extreme Conditions: These valves provide consistent, leak-free sealing and operation in cryogenic temperatures, ensuring system safety and operational efficiency.

High Durability: The use of low-temperature-resistant materials increases the valve's longevity, making it resistant to the wear and tear that would otherwise be caused by extreme cold.

Seamless Operation: With a ball valve design, these valves offer smooth and reliable opening and closing functions, which is crucial in operations where safety and performance cannot be compromised.

Easy Maintenance: With simple operation and minimal maintenance requirements, these valves are designed for long-term reliability even in challenging low-temperature environments.

Versatility in Cryogenic Applications: The valve’s design allows it to be used in a wide range of industries, from LNG plants and storage tanks to chemical production and industrial gas transport, providing excellent flexibility across applications.
