Got compact non return valves from McMaster Carr and was able to easily hand pump over 160psi with no precharge, but volume is really small, will take a long time to fill a tank of any volume. :(

Similar to the air bombs in my arms. Unfortunately, it only drives small volume of air. To fill a deposit does not reach unless you are all the afternoon giving and giving pumping :?

In this type of regulator, is it possible to use between 400 and 500 psi in the tank and between 100 and 150 psi at the exit? I have the possibility of getting one but I do not know if it is possible to use it within this range, which is what I need specifically :roll:

The critical element is the spring pushing against the pressure, as these things are typically made for a 850 psi output then the stock spring is going to be far too strong.

You can find low pressure kits for certain models but the output is typically higher than 150 psi.

Something like this will probably work better but make sure you have a safety pop-off or burst disk in your circuit, if a seal fails inside then it's full reservoir pressure to your system.

I bought several of these, work wonders. Air flow is healthy and stable.

It is definitely the best option for my project. :) Thank you
