Bob is exactly right, I was using the term "ball" generically. It is a plunger with a beveled sealing surface. Here is a pic of the parts in mine. If you zoom in on the hole all the parts go into, you can just see where the diameter reduces way down in there. This is the inner seat that the beveled sealing surface of the check"ball" rests on.. Down thru that smaller diameter hole lies the top of the relief valve assembly...
