regulator guage shows same pressure as tank guage

I have 60 gal vertical air compressor I came out of the tank put a cut off then a water filter and then a regulator with gauge regulator seams to work but gauge on regulator shows same as tank pressure gauge

Donnie, are you saying that when you turn the regulator knob to adjust the pressure setting of the regulator, the pressure stays at the tank pressure?

Regulator Not Working

Brand new, never used (sat in a box for a while) c2002 type 3.

Unregulated pressure is fine. Controlled or regulated pressure sits at zero.

I tried manipulating the knob both directions and nothing worked.

I unscrewed it completely to get a look inside and it seems like the diaphram?? (not sure what the part is since I haven't been able to find it on a diagram) is broken. Is there anyway to just get this part instead of the whole manifold assembly?

Thanks
Dan

Dan, from the pictures of the manifold assembly I was able to find, I could not tell if the various components are threaded onto the manifold, or, if the entire manifold is one cast piece.

If it is one cast piece, then you will be replacing the manifold.

If the manifold can be disassembled, then you can replace just the regulator by acquiring a similar one from any compressor or compressor parts store.

I do not know of any sources for just the air regulator components to allow you to rebuild the regulator.

Regulator Capacity

by Bob
(Gravitate, AR)

My compressor operates at 175 lbs. of pressure. Can I use a regulator that is rated at 150 lbs of air pressure?
__________________
What you are saying is that the compressor has the ability to pump up to 175 PSI. The regulator has an upper capacity of 150 PSI.

This means that if you wanted to dial the pressure up to, say, 160 PSI, you couldn't as your regulator wouldn't go that high.

Since the regulator rated for 150 PSI should have a burst safety pressure rating much higher than that, I don't believe you would be in danger if you used the 150 PSI regulator.

What you will likely find though is that the regulator will not work properly as you are overpressurizing the spring and diaphragm, and if it works, I suspect it won't work very long.

It were me, I'd get a regulator rated for 175 or higher.

Pressure Regulators

by Nikhil Gupta
(New Delhi, India)

I'm trying to design a methanol production plant from CNG. Now for this I'm using CNG by connecting a fuel compressor to the nearest underground natural gas pipeline distribution system. Now what I want is to get the pressure at about 40barg, whereas the compressor raises the pressure till 250barg. Now can I use a pressure regulator in this case? If yes, what kind of air pressure regulator can be use?

An intriguing question, Nikhil. Since I am reasonably conversant with compressed air, and not at all comfortable with natural gas systems, I am not qualified to answer.

I will post your question in the hope that others more knowledgeable than I will comment.

Good luck.

Bill
