Product Description

Product Description

Mainly used for precise regulation and shut-off of ultra-low temperature media, with operating temperatures as low as -196°C. Suitable for ethylene, liquefied natural gas, air separation, and pressure swing adsorption oxygen production low-temperature installations. Every cryogenic control valve produced by FITER undergoes oil-free degreasing treatment during installation, with each component subjected to cryogenic treatment before fine processing to prevent cracking during actual use. Before delivery, the valves are tested for pressure and leakage in liquid nitrogen to simulate cryogenic conditions, with helium gas used for gas tightness testing.
