I need good control over air pressure with high flow. I have a 1" pipe with 120 PSI incoming. I need to control the pressure to 0-5 PSI with "good" flow. I bought a regulator (0-12 PSI) from McMaster.com and that seems to be good. I bought a gauge (0-5PSI) and that is good. My issue is that I need to protect the gauge from over pressure.
I bought an adjustable pressure relief valve that has a simple adjustable spring. The issue is that if it starts popping open at 1 PSI it does not open fully. If the operator turns the pressure up then the pressure starts rising in the system possibly ruining the gauge.
I looked for pilot operated relief valves but all I seemed to find were too high a pressure and too big a pipe size.
Does anybody have any suggestions for saving that gauge?
