Cryogenic Valves

The Microfinish cryogenic valve line is available in

trunnion mounted valve type up to 24 inch

(DN 600) and floating ball type up to 10 inch
(DN 250). The various configurations are

available in reduced bore and full bore

designs, and pressure classes from ASME 150

to 2500 (size dependent). The valve must

function properly at temperatures as low
as -269°C/-450°F and precise tolerances are

set for those parts to be subjected to thermal shock and shrinkage.
