Tuning Setting External Regulator

[CanMike]

Quick question for the Group. I have a general idea what to do but it involves making some parts. Wondering if there is a better simpler solution.

I have a regulator on my tank valve that can be set to 150-300 BAR.. I want to set it to 175-180 BAR (2600 PSI). I turned it all the way to the 150min, so now have to work it back up.


What is best way to do this OFF the gun as I don't want to blow the seals in case something goes wrong. I want to set it and then hookup to gun. Bottle has 4000 PSI in it currently.

This is the valve I have.

Thanks

bleed off a little air until it settles down to the lower pressure and then slowly turn it up.. would be great to have a larger gauge to verify the pressure, those tiny gauges are very hard to read small increments.. after you get it up to where you want bleed a little more air, just to make sure it's where you want..
it's what I do with my oxygen and acetylene torch..

Ya definetly got the bleeding air part.. But How do you keep pressure. I was thinking I need to plug the output 99% so only a touch of air escapes so then I can get a reading of the output pressure gauge.

Yes I agree the gauges suck, but if I get it 95% there I can do a bit of fine adjustment when hooked into rifle.

I forgot that with the torch I can adjust flow on it.. surprising even with the big regulator when you operate it the pressure is slightly lower.. well that's off topic..
anyway yes you would need a valve on the end so you can turn it on and see what the gauge says.. although you likely have a bleed screw when you finish filling your gun..if that's the case all you need is a deadhead plug.. one came with my compressor, you just plug the line.. it's a quick disconnect.. and turn on the compressor to see if the auto shutdown for pressure is good.. so you could just put one of those plugs in your fill line..test and set regulator pressure, shut off the air and then bleed it.. should be fine..
if you don't have a plug, well I suppose you could set it low and then hook up to your gun and slowly turn up the pressure until it's where you need it to be..
yes my Omega trail charger came with a deadhead plug.. you didn't say if you have a compressor, if you do, maybe it came with one..or you should be able to easily order one.
