I am looking for a U.S. company that makes cast iron or ductile iron globe valves 3-12 inch. Seems every company I take with now makes the valves in China.

I'm not sure you could find a valve manufacturer that still uses US foundries to pour cast iron. Most of the foundries left in the US are either too small or pouring low cost cast iron valves is not worth their time.

If I am not mistaken there is an exception clause in the buy American act something along the lines of allow exceptions if
domestic items are unavailable at a reasonable cost or quantity. but to be honest I have no idea on how that works.
