The listed=20 "CV" rating is defined as: "the amount of water (in gpm) that will pass = through a=20 fully open valve at 1 psi with 1 specific gravity=20 (60=B0 F)."   Since the rating=20 for the 1.25" valve was 44, and you'll have one of these for each pump, = it seems=20 reasonable to me.   
 
Personally, I=20 may try to make valves that can be welded to the radiator, so they don't = take up=20 as much space.  I haven't really collected enough data to know what = I'm=20 going to do yet.
