Our A351 CF8/CF8m Cryogenic Control Valves are the epitome of precision, crafted meticulously for managing and halting the flow of ultra-low temperature media, operating in extreme conditions with temperatures plunging to -196°C. These valves are the ideal solution for a range of specialized industrial applications, including ethylene processing, liquefied natural gas operations, air separation units, and pressure swing adsorption oxygen generation systems. Each valve is engineered to the highest standards by FITER, undergoing an oil-free degreasing process during assembly to ensure purity and performance. To bolster durability, every component is fortified with cryogenic treatment before the fine machining process, effectively preventing any risk of cracking in real-world use. We guarantee reliability by subjecting each valve to rigorous testing prior to delivery. This includes pressure and leakage assessments in liquid nitrogen to perfectly emulate cryogenic environments, along with helium gas tests to ensure impeccable gas tightness.
