Kobalt Air Compressor K7580v2 PRV pops off immediately
Unloader valve for compressor
2 stage cast iron 5hp 175lbs 80 gal. This unit has 2 safety valves. One of them pops off immediately when you power the unit up. description on valve is BREV PV4,5 BAR D=6,8
I don't find the valve on parts breakdown. Is this the unloader valve?
I can't locate a clear picture of this compressor Walt, so I cannot pinpoint the two PRV's. The photo you supplied sure looks like one.
You have two of them on your Kobalt air compressor. Where are the two located, and which one is this one, please.

operates normal, does not pop off
Reply to Bill w/photos of K7580V2 safety Valves
Thanks. I had just responded to your other post. Thanks for the photos.
The first photo, the one you say "operates normal, does not pop off" is the typical PRV that is reading the pressure in the tank. If the tank pressure exceeds the setting, this PRV opens and bleeds off air.
The photo that "valve is hidden between compressor and pully" is also a safety valve. I know this valve is available for about $15.00, but I cannot see where it is installed in the plumbing. You say it's between the compressor and the pulley, but it must be on an air line?
I believe yours is a two stage air compressor, and I suspect that the safety valve in question is in the line between the first and second stages.
If that is correct, that it pops off on start up suggests that the air cannot get into the second stage cylinder, and that suggests that your intake valve on the second stage has failed, and won't allow the air to flow, instantly increasing the pressure in the line and blowing off the safety valve.
Please let me know if the location I describe makes sense.
my kobalt oilfree compresser sparks when i start it what can be the problem
it is a 1.5 hp 155 psi stand up compressor
What is sparking Isaac?
Are the sparks coming from the pressure switch or the motor.
If the pressure switch, replace it.
If the motor, consider getting a load test and the motor rewound.
26 gal. was working fine for a few years, now all of a sudden it isn't.
I have the Kobalt model # 37296-26 gal. and all I use it for is inflating auto tires.
All was well until a week ago; I needed it and when I flipped the on switch, nothing happened. It clicked and then blew the 15 amp breaker. Re-set the breaker and the same thing; over and over. Not sure what to do next.
A good start Mike would be to visit the troubleshooting section on the sitemap page and look at the pages that have to do with air compressors that blow breakers on start up.
After that, add a comment here with specifics about what you found, if anything, and we'll press on.
My 8 gallon oil free air compresser never shut off Did I miss something.
My 8 gallon oil free air compresser never shut off and when it's on the gauge needles vibrate but do not move. It holds air and works just doesn't shut off like its suppose to.
Jason, don't know if you missed something or not.
However, I do believe your air compressor has a problem.
If the air compressor runs and runs, doesn't shut off, and the tank pressure gauge stays almost in one place, then the air that your compressor pump is trying to get into the tank isn't getting there.
See the troubleshooting section on the sitemap page and read the info about why air compressors run but don't build pressure, for some tips.
