This one does regulate. I have mine set to 2900 psi for the max fill of my pistol, and it never overfills it. It is now the only way I fill that pistol, as it has a tiny reservoir (~27cc) and it always tool great control even with a slow fill valve on a Guppy tank to avoid over filling.
I will point out that since it is regulated, there is extra internal volume in it over a standard valve that is lost to venting, and on a small tank that could matter. I just use my Edgun Easy fill on it when I am doing lots of shooting, then I don't have to vent it to remove the line from the gun, and I get many more fills out of the small tank. But if you are leaving it hooked up tethering that would be no issue.
