Cryogenic Control Valves with ANSI 150-1500 Ratings for Safety with ANSI 150-ANSI 1500

Introducing our Cryogenic Control Valves, engineered with precision to offer unmatched regulation and secure shut-off capabilities for ultra-low temperature media. With the ability to efficiently operate in extreme environments down to -196°C, these valves are perfectly suited for critical applications, including ethylene processing, liquefied natural gas systems, air separation units, and pressure swing adsorption oxygen production at low temperatures. Each valve, crafted by FITER, is meticulously subjected to an oil-free degreasing treatment during the installation process. Moreover, every component is carefully cryogenically treated prior to fine machining to ensure robustness and prevent any potential cracking during actual operations. Emphasizing quality and reliability, our cryogenic control valves are rigorously tested for performance, enduring pressure and leakage assessments using liquid nitrogen to emulate authentic cryogenic conditions. Additionally, we employ helium gas testing to guarantee exceptional gas tightness, ensuring optimal functionality in all operational scenarios.
