I found the make but still need to find out the model number.


Home Depot's web site has a lot of them - after you click on the
product - there is a link to "specifications" that might help.
... graphs for flow characteristics; pressure ranges and limits, etc
Here's just one example ..

Thanks for the link.
Now that I'm thinking about this, I wonder how a pressure regulator can
regulate water pressure when no valve is open.


A couple more web links, found through a very quick google search.
