SYR-SYD Series Cryogenic Side-Entry Trunnion Ball Valve

Features & Benefits

Cryogenic side-entry ball valves are manufactured for extremely low temperature and cryogenic applications.Valves are designed with an integral bonnet extension which prevents cryogenic liquids from reaching the stem packing by enabling the liquids to boil and convert to gas. This minimizes the energy loss along the extension and protects the valve from malfunctioning. The structural integrity of the valve reduces any thermal deformation of internal components caused by temperature variance to a minimum, ensuring the highest level of performance for tight shut-off in critical LNG fields.
