Compressed air regulator

[92saturnsl2]

I have a simple problem-- 50-some gallon dual stage air compressor that gets to 145psi. I need to regulate it down to ~90 psi for my air tools.

I bought this device: https://www.menards.com/main/tools/...-regulator/r3802g/p-1444451508351-c-12917.htm

Plumbed it in just after the tank/compressor and all it does is two things:

A) doesn't pass air if the input pressure is over set regulator pressure.

B) if you dial it down below input pressure, it will pass air while bleeding the tank down to its set pressure.

I thought a regulator was supposed to take a higher input PSI and output a set lower PSI. What does "intermediate" mean as it pertains to regulators, perhaps I bought the wrong one. For what this thing does, I can just set my air compressor to stop at 100psi and do the same thing.

Sounds faulty. Look into Milton.

I bought the regulator, water separator, filter combo. Going on 6 years issue free.

Does your compressor not have two gauges? One for tank and the other for tool?

Not sure to your specific regulator, but it should be limiting psi.........try starting with a full tank, at full pressure, and the regulator screwed all the way down......then slowly unscrew the regulator until the pressure lowers to your liking. If it does not do this, I would say that there is an issue with your regulator. You may need to flow some air through line like with a blow gun, as you adjust the thing.

Is there a flow direction (in-out) on the valve body that you followed?

After a lot of frustration, it was a faulty regulator. Returned it for a new one that works like it's supposed to.

There's a diamond on the output side (per the instructions) so it was near impossible to install it incorrectly.

I don't run a main regulator, Any air tool worth having will handle 150-175psi, On sensitive stuff....I use a regulator at the hose, Which for me is a little paint gun & Transmission solenoid testing equipment.

That really sounds like it was plumbed in backwards. If it has more than two ports, exactly one will be the inlet and the others are multiple outlets in parallel.

Nope, the OP returned the defective regulator and installed the good replacement. His Masterforce regulator only has one marked inlet and one outlet as shown below.
