Cryogenic Ball Valve

South American valve is a top Cryogenic Ball Valve supplier in Peru. A cryogenic ball valve is a type of valve that is designed to work in extremely low temperatures, typically below -40°C. Cryogenic ball valves are commonly used in industrial applications such as liquefied natural gas (LNG) processing, aerospace, and medical research.

The main component of a cryogenic ball valve is a ball-shaped plug with a hole through the center that allows for the flow of fluid.

The ball is rotated by a lever or actuator to control the flow of the fluid. The valve is designed to prevent leaks and ensure reliable operation even in harsh cryogenic environments. Cryogenic Ball valves are typically made of materials that can withstand low temperatures, such as stainless steel or high-performance alloys. They are also often designed with extended stems to allow for easier operation while wearing thick insulated gloves. Overall, cryogenic ball valves play a critical role in many industrial applications where precise and reliable flow control is essential in extreme low-temperature environments.

Advantages

• High flow capacity: Cryogenic ball valves have a full-bore design, which means the ball opening is the same size as the valve bore. This allows for high flow rates and minimal pressure drop.
• Tight shut-off: Cryogenic ball valves have tight shut-off capabilities, ensuring that no fluid leaks through the valve when it is closed. This is essential in industries such as liquefied natural gas processing, where leaks can be dangerous and costly.
• Low maintenance: Cryogenic ball valves are low maintenance and can operate reliably for long periods with minimal upkeep. This is important in applications where valves may be difficult to access for maintenance.
• Wide temperature range: Cryogenic ball valves can operate in a wide temperature range, from ambient to extremely low temperatures, making them versatile in a variety of applications.
• Corrosion-resistant: Cryogenic ball valves are often made of materials such as stainless steel or high-performance alloys, which are corrosion-resistant and can withstand harsh environments.

Applications

• Cryogenic ball valves are used in LNG storage tanks and transportation vessels to control the flow of LNG, which must be maintained at extremely low temperatures to remain in a liquid state.
• Cryogenic ball valves are used in spacecraft and rocket engines to control the flow of cryogenic propellants, which are used to power the engines.
• Medical Research: Cryogenic ball valves are used in medical research applications, such as cryogenic storage of biological samples and specimens, to control the flow of cryogenic fluids.
• Industrial Gasses: Cryogenic ball valves are used in the production and transportation of industrial gasses, such as nitrogen, oxygen, and argon, which must be maintained at extremely low temperatures to remain in a liquid state.
