It makes one wonder about the quality of valves in today's advanced technological world, or maybe the original selection of valves........I served on some older ships in the Royal Australian Navy........I cannot recall ever replacing 10", 12' or larger suction or discharge valves........they were always refitted by ship's staff during the ship's dry docking periods......the only thing that I ever remanufactured for these types of valves was a couple of valve spindles (they had become porous over 20- 25 years of service)........we recut valve seats, lightly machined valve faces, etc., if required, and lapped the valves......these valves were all manufactured from a good quality marine grade bronze. All valves were globe type, screw down/screw lift valves.

I wonder if the valves on these USN vessels are butterfly valves.........that could explain a great deal???
