Our High-Quality Cryogenic Control Valves in A351 CF3/CF3m Materials are meticulously engineered for the precise control and efficient shut-off of ultra-low temperature media, capable of functioning optimally at extreme temperatures down to an astonishing -196°C. These valves are indispensable for applications involving ethylene, liquefied natural gas, air separation systems, and the sophisticated operational demands of pressure swing adsorption oxygen production low-temperature installations. Every valve crafted by FITER is subject to an innovative oil-free degreasing process during its assembly, ensuring the highest standards of cleanliness and performance. Moreover, each component is rigorously treated under cryogenic conditions prior to the fine-tuning and machining process, effectively thwarting any risk of cracking under actual operational environments. Prior to dispatch, our valves undergo stringent pressure and leakage testing immersed in liquid nitrogen to authentically replicate the harsh, cryogenic conditions they will face. Additionally, helium gas is used to perform rigorous gas tightness testing, assuring unparalleled reliability and safety.
