Does anybody know what sort of flow loss one could expect by using a ball check valve?
If I install a 3/4" (20mm) ball check valve on a hose running about 1500lph, I would like to think that the flow doesn't take too much of a hit.
I understand that spring check valves require considerable "cracking" pressure and therefore flow takes a large hit.
I also understand that swing check valves would be a pretty good choice for what I am doing here, however, it seems they are much harder to get a hold of here in Australia, whereas ball check valves are pretty easy to find.
How does a swing check and ball check valve compare in terms of flow loss?
