Our exceptional Customizable Cryogenic Control Valves are meticulously crafted for the precise regulation and reliable shut-off of ultra-low temperature media. Expertly designed to withstand extreme conditions, our valves operate at temperatures as low as -196°C, making them ideal for critical applications in ethylene processing, liquefied natural gas, sophisticated air separation systems, and advanced pressure swing adsorption oxygen production installations. Each valve from SNT Machinery (Qingdao) Co., Ltd. embodies the pinnacle of engineering excellence, benefitting from an oil-free degreasing treatment during its installation phase. Furthermore, every component is subjected to a rigorous cryogenic treatment before undergoing fine processing, effectively ensuring resilience and preventing cracking during real-world operation. Prior to delivery, our valves undergo stringent pressure and leakage tests in liquid nitrogen to accurately simulate cryogenic environments, with helium gas employed for rigorous gas tightness testing, guaranteeing reliability and superior performance.
