Abstract:

Five divers non-return valves for use with standard air and helium hard-hat diving were provided in response to specifications provided by Navy Experimental Diving Unit. The ability of the valves to seat at low pressure differentials after many cycles of operation, lack of valve clatter, and ability to pass the required air flow were satisfactorily demonstrated in a series of laboratory and operational tests.
