Cryogenic Ball Valve

Product Overview

Cryogenic ball valves are designed for use in extremely low-temperature environmental applications, such as cryogenic systems. These valves provide reliable shutoff, control and isolation of fluids at temperatures down to -196°C (liquid nitrogen temperature). They are made of special materials to withstand the physical stresses and performance requirements associated with cryogenic and cryogenic applications.

Cryogenic ball valves are commonly used in industries such as liquefied natural gas (LNG) transportation and storage, cryogenic research and industrial gas applications. Their ability to function properly at sub-zero temperatures is essential for the safe and efficient handling of fluids such as natural gas, liquefied gases and other cryogenic media.

Main characteristics

Low Temperature Performance: Designed to operate efficiently at low temperatures, ensuring tight sealing and reliable performance down to -196°C.

Specialty materials: The valve body and other key components are made of stainless steel, carbon steel, and low-temperature-resistant alloy steel, such as 304L, 316L, or LCB, to ensure strength and durability in freezing conditions.

Airtight Seal: The cryogenic design ensures that the ball valve provides airtight shutoff even in extremely cold conditions, reducing the risk of leakage and ensuring system integrity.

Low-friction operation: The valve's ball and seat have a low-friction design that ensures smooth opening and closing and avoids the risk of freezing or seizing common in cryogenic applications.

Fire Resistant Design: Typically equipped with fire resistant seals and features to ensure that even in the event of a fire, the valve will continue to provide a reliable seal and prevent leakage.

Full bore design: Most cryogenic ball valves feature a full bore design that provides unobstructed flow paths and minimizes flow resistance and pressure drop, making them ideal for high flow applications.

Extended Stem: To ensure that the valve can be operated remotely in cryogenic environments, many cryogenic ball valves are fitted with an extended stem to isolate the operator from the freezing environment.

Product Advantages

Reliable performance in extreme conditions: These valves provide consistent, leak-free sealing and operation at low temperatures, ensuring system safety and operational efficiency.

High durability: The use of low-temperature resistant materials extends the service life of the valve, enabling it to resist wear caused by extreme low temperatures.

SEAMLESS OPERATION: These valves feature a ball valve design that provides smooth and reliable opening and closing, which is critical for safety and performance-critical operations.

Ease of Maintenance: These valves are simple to operate, require low maintenance, and operate reliably for long periods of time, even in harsh, low-temperature environments.

Versatility for cryogenic applications: The design of the valve makes it suitable for a wide range of industries, from LNG plants and storage tanks to chemical production and industrial gas transportation, providing excellent flexibility in a variety of applications.
