These exceptional Heavy-Duty Cryogenic Control Valves, meticulously crafted by SNT Machinery (Qingdao) Co., Ltd., are engineered for the precise regulation and reliable shut-off of ultra-low temperature media. Capable of functioning at extreme temperatures as low as -196°C, they are perfectly suited for challenging applications like ethylene processing, liquefied natural gas management, air separation, and pressure swing adsorption oxygen production in low-temperature environments. Every valve produced by FITER is subject to an advanced oil-free degreasing operation during assembly, ensuring optimal purity. In addition, each component undergoes cryogenic treatment prior to precise machining, effectively preventing any possible cracking during rigorous service. Prior to dispatch, these valves are rigorously tested under simulated cryogenic conditions using liquid nitrogen to verify optimal pressure and leakage performance, while helium gas is employed to ensure superior gas tightness.
