The brass ones will have the same sort of losses a PRV will have, so you need the headroom to work with it.

He sold the house now the new owners cant sleep with the water hammer and pump cycling. they told me they had to shut it off last night so they could sleep

Use CSV1Z for 1-25 gpm. The CSV2W does 5-50 gpm.
Make sure and look at both pressure loss charts because they are additive.
I'd probably use the CSV2W for this application, unless the irrigation zones are very small.

I have installed several plastic cycle stop valves and haven't had one leak yet.
The Cla-valve works well with higher volumes too but are also costly.
Pitch the plastic cycle stop with the idea it isn't as costly and is more of an experiment to determine compatibility - or replace the pump with one correctly sized for the application.
I just thought of something else, is there anyway to plumb in a pressure relief valve back to the well? This would temporarily correct the bulk of the water hammer issues.
Nice Try = You Suck Spelled Differently
