Any recommendations on a good quality spray gun regulator?

I’m setting up my iwata w400 in prep for spraying later this month but need some guidance on a regulator that will work with high cfm and does a good job regulating the air pressure. Alot of what I’ve seen look to be air adjusting valves that are being passed off as actual regulators And since most of these guns aren’t designed to see line pressure, I want a true regulator as I want to keep line pressure at 135psi. I have a cheap HF one and the one that came with my tpc primer gun but no idea if these are any good. Any recommendations?
thanks!
 
If you're talking about a regulator that attaches to a spray gun, I use RTI. It is a diaphragm regulator, not a cheater valve. I set my wall regulator at 120 psi and have had no issue with the RTI blowing out.

Most any real regulator types will. Devilbiss, Iwata, HF.
You referring to a choke valve which is the last thing you want.
I ditched mine long ago and use my wall regulator in my spray area or booth and a simple tee fitting to set what I want from the wall ensuring I Know exactly what is going into my Gun because I didn't like all the hardware hanging out. Remove it and shoot. Nothing but the Devilbiss bulb air filter and the gun. I need a touch more air,just watch the regulator Guage.
Just saying.

I'm trying to wrap my head around how you have this set up.

How much air pressure do you have from your compressor to your wall regulator?

This is where I get lost. Where are you attaching the home made regulator, at the gun and using the wall regulator to adjust psi to the gun? Then removing the home made regulator?
 
At the Gun. Hooks between the gun and hose coupler.
Some regulators can build pressure on the gun when the trigger is off and blast out for a second until the reg catches it. So if your not careful, you'll do something bad. My wall regulator is constant so when I pull the trigger I get no surprises like some of the gun regs will.
I just hate a bunch of 'stuff hanging down in the way and adding weight too.
Plus, I have a 90 degree ell on my gun Inlet to kick it back out and not drag from the bottom.
Generally you have your offhand holding the hose up and away from the work,slung over the shoulder,etc and I just find it easier because it's already perpendicular to the work.
Everyone has quirks.

It's not a Regulator. Just a tee with a Guage with male and female connections. 1 is 1/4" and 1is 3/8" hvlp.My Regulator is on the wall in my "booth" and I have a "travel Regulator" for outdoor use. My Supply air is 125# depending on what I'm doing. I had gun regulators but 'something was always screwing up,leaking,in the way and said the he'll with this.
