    J: what do you mean by "pop the cap up 1/8"? Which cap? The CAP60P-OF I have only has 2 red rotary knobs. I'm having a similar problem; my tank will only fill to around 120psi then shuts off. It used to pump up to 130psi (the max). Thanks.

YOU DO NOT ADJUST THE PRESSURE RELEIF VALVE. IT IS PROTECTION DEVICE SET BY YOUR TANK PSI. I THINK YOUMEAN THE PRESSURE REGULATOR. YOU TYPICALLY POP THE CAP UP 1/8" AND ROTATE THE KNOB. CLOCKWISE TO INCREASE. YOU MAY HAVE TO BE USING SOME AIR ( BLOWGUN? ) FOR THE GAUGE TO DROP FASTER BUT IT SHOULD DROP ANYWAY. HOPE THIS HELPS.

Leaking around Pressure Switch. Ordered & replaced switch but still leaking


Some pressure switches have a valve that reliefs the compressor head pressure when the motor stops and closes the head pressure relief valve when the motor runs.
There is a check valve that keeps air pressure from coming back to the compressor head and the relief valve.
I think the check valve is leaking tank pressure to the relief valve and compressor head.
The check valve is where the pressure switch mounts on to and it mounts threaded on to the compressor tank.
Try replacing the check valve

POP OFF VAVLE ON HEAD KEEPS POPPING UP


The over-pressure relief valve may be defective if the valve is opening before the desired tank pressure is reached. If not, then the shut-off pressure adjustment (if there is one) may be set wrong. You'll need to find out from the manufacturer exactly what static tank pressure the compressor is designed to provide and then determine if it is working correctly. If so, then the relief valve might be defective. DO NOT attempt to defeat the relief valve under any circumstances - it can result in compressor damage or a dangerous tank failure.

My compressor is building to much pressure and blowing out the relief valve. what do I check


You didn't give the model of your compressor so, for an electric model: Check your gages while the tanks are filling. If the pressure gets to the rated high pressure level for your model and keeps going until the relief valve pops, the problem is with the pressure switch. It isn't turning the motor off when it's supposed to. If the relief valve pops before getting to the max pressure the tanks are supposed to be at then the spring in the valve is broken or weakened to where it pops too early. Replace the relief valve.

Is the reed valve part of the pressure switch


relief valve should only open in a over pressure condition. If it is opening prior to reaching pressure ....replace it.

How do i adjust the pressure relief valve so it quits poping out befor the compresser shuts off


There is no adjustment on the relief valve. They are preset at the factory. You might have a problem with the pressure shut off being set too high on the upper limit causing the pop off to activate before the motor shuts off.

I have a C2006 Type 4 Porter Cable pancake compressor which will build pressure all the way up to 150psi then cut off as it should but there will be a loud hissing and pressure drop until the cut on...


first you have a reciprocating pump and the hissing you ear probably comes from the unloading valve on the pressure switch(it will look like a bike tire valve)if there is air coming out the valve when the compressor is off it probably means you have a bad check valve.This valve is use to unload the pressure inside the pump for an easy start .a motor always drive more amps on start up if you cant unload this pressure you will trip the overload(you probably have a reset button on your motor)check the specs on your pressure relief valve ,its a small pump maybe its just adjusted to high.in this case your pressure relief valve will open .If the pressure is fine and there is air coming out the relief valve then you have to replace it!to adjust your pressure turn the screw on your pressure switch clockwise to increase and counterclockwise to decrease .usually you have a 30 psi between cut-in and cut-off called the pressure differential.It can be adjusted on some pressure switch.be sure you put some teflon tape on the treads if you replace something to avoid air leaks.hopes this help!

How do you adjust the pump pressure valve on a Emglo model KU


do you mean the relief valve. it is factory set for your safety and the sefety of the equiptment. also known as the safety relief valve.

if you are talking about working pressure you need to adjust that with the air regulator.

if you are talking the cut out pressure sensor, again this is also factory set for safety. if your equiptment is designed for 110 psi then when your resivor reaches that set point it should cut the motor off and stop running.

My Bostich CAP60P compressor will build pressure to about 40 pounds (tank pressure), and then keep running but not build more pressure or build it very slowly. No leaks.


sudden loss of capacity like that usually indicates broken or leaking valves in the head, or a blown gasket between inlet and discharge side of the head. if nothing is found there, then look at the piston and or cylinder bore for damage.

The compressor relief valve keeps popping, compressor runs


What pressure is it popping off at? You might have to adjust the pressure switch to a lower setting.
