ABSTRACT:
The temperature actuated valve comprises a thermally more sensitive valve stem than the valve housing. The stem expands at a faster rate and causes vapor entering the valve to be gradually vented through an orifice of gradually increasing area as the temperature of the gas increases. It has application as a cryogenic phase separator valve which allows any cryogen vaporized in a cryogen delivery system to be automatically vented from the valve and to allow for an even flow of liquid to the spray nozzles and onto products of cryogenic freezing tunnels.
