Discover the unparalleled precision and reliability of our Durable Cryogenic Control Valves, meticulously crafted from robust A351 CF8/CF8m/CF3/CF3m materials. These valves excel in the precise regulation and effective shut-off of ultra-low temperature media, boasting an impressive operating temperature range that plunges to a frigid -196°C. They are ideally suited for applications involving ethylene, liquefied natural gas, air separation, and pressure swing adsorption oxygen production in low-temperature installations. At SNT Machinery (Qingdao) Co., Ltd., each cryogenic control valve undergoes a specialized oil-free degreasing process during installation, ensuring purity and performance. Furthermore, every single component is subjected to an advanced cryogenic treatment prior to fine processing, a crucial step to prevent any cracking during actual use. To guarantee unrivaled reliability, we rigorously test each valve for pressure and leakage using liquid nitrogen to faithfully simulate cryogenic conditions. Additionally, helium gas testing is employed to verify gas tightness, providing assurance that our valves meet the highest standards of quality and performance.
