Cryogenic treatment is a process used to improve the mechanical properties of metals by subjecting them to ultra-low temperatures. Cryogenic valves are valves that are specifically designed to operate in extremely cold temperatures. Cryogenic treatment for valves involves exposing the valve components to temperatures as low as -196°C in liquid nitrogen. This process helps to increase the valve's durability and resistance to wear, corrosion, and fatigue. Cryogenic treatment also enhances the valve's dimensional stability and reduces internal stresses, resulting in better performance and longer service life. These valves are widely used in industries such as aerospace, pharmaceuticals, and gas processing.
