Our ANSI 150-1500 Rated Cryogenic Control Valves are the epitome of precision and reliability, designed specifically for the meticulous regulation and secure shut-off of ultra-low temperature media. These state-of-the-art valves operate efficiently at temperatures as frigid as -196°C, making them an ideal choice for critical applications such as ethylene processing, liquefied natural gas operations, air separation, and pressure swing adsorption oxygen production in low-temperature environments. Each cryogenic control valve crafted by SNT Machinery (Qingdao) Co., Ltd. through FITER is meticulously subjected to an oil-free degreasing treatment during installation. To ensure utmost quality and performance, every component undergoes cryogenic treatment before being finely processed, eliminating the risk of cracking under real-world conditions. Prior to delivery, our valves endure rigorous testing for pressure and leakage using liquid nitrogen, simulating the most demanding cryogenic scenarios, and are further scrutinized for gas tightness with helium gas to guarantee unparalleled reliability.
