Cryogenic Trunnion Mounted Ball Valve

As the professional valve manufacturer, we would like to provide you the cryogenic trunnion mounted ball valve, which is a special valves used for the low working temperature on the chemical industry or cold environment, per design standard API 6D&ASME B16.34 and cryogenic testing procedures, the limit temperature could be as low as -196℃.

Cryogenic floating ball valves are used for low temperature working condition, especially for some hazard media, such as liquidized nature gas. Our company has been experienced in the design, manufacturing, inspection and testing of cryogenic ball valves.
