Question about Porter Cable C2002-WKR 150 PSI, 6 Gal. Oil-Free Compressor w/13 Piece Hose & Accessory Kit

1 Answer

Why does the safety valve go off before the pressure switch on a porter cable 80 gal air compressor

I have a porter cable 80 gal 6hp air compressor and the safety valve on top of the pump lets air out before the tank reaches its correct psi. The pressure switch is set to 175, however the safety valve activates at about 150 or even less. How do I fix it?

    Is the spring loaded valve on top of the pump called a regulator or a safety valve?

The maximum pressure on most small compressors is 10 bar or 1000kpa which is about 145 psi in the old language most safety valves are set to 150 psi. I suggest you get some one to reduce the pressure switch setting. Running a compressor at elevated pressures does not give you any more air. A reasonable pressure for small compressors is 120 psi

Porter cable 6 gal pressure switch. safety valve blows when tank filling


Depending on the pressure in the tank when the safety valve releases,the problem is likely your pressure switch. If the pressure is at or above 160 psi when it blows, then the problem is the switch.If the pressure is lower, then it is likely a faulty safety valve. There are about 8 versions of this machine. check on dewalt service net for the correct part. you may need to check ebay if the part is nla thru dewalt.

Pressure switch can be adjusted to lower pressure (most are set between 125 and 150) however could be faulty safety valve if safety open below 165psi. Some things to check. Safey has pressure setting stamped on side. Check range of safety and compare to tank pressure when safety opens. Check that pressure switch contacts are not welded (unplug unit and remove cover to switch, look for contacts thru side of switch). If you suspect that switch is faulty, buy universal switch from ebay or other suppliers making sure of pressure range and fittings. Good luck

where the plug in goes into the pressure switch you can take the cap off and you will see the electrical points and on the inside of the plastic cap it will you show you the two screws to adjust there. one screw will be to raise or lower the min and max pressure equally and the other is to adjust the differential between them. But make sure not to exceed recommended pressure of the compressor or you will blow safety valves, the safety valve will say what pressure it will go off at

Compressor keeps blowing release valve


Compressor pressure switch not working properly. Remove cover over pressure switch. Drain air out of tank. pressure switch contacts should open. If contacts do not open they may be stuck or welded close. Remove power and gently pry contacts apart. If they where welded together this will correct. If this doesn't correct replace pressure switch

I believe you have a head valve or piston ring problem. The parts you replace are suppose to leak. It is a safety feature that doesn't allow the motor to burn up before the pump warms up. Kind of like a soft start feature. If you look on the breakdown part number 107 Kit Valve Plate is what you need to inspect. Sounds like your valve plate is either worn or damaged. If you go into the pump you will have to get part 103 also which is a gasket kit. Or you can try to salvage the old gaskets.
If the valve plate is ok you will need to inspect the rings that go around the pistons. Some times you will get one that gets brittle and breaks off scarring the cylinder. Look for these two things, I am pretty sure one of them is the problem with your compressor.

Compressor blows off, does not maintain pressure


Hi there. This is normal. The pressure is set to stop at around 120-140 PSI as a safety measure. It probably kicks in again around 80 PSI so as to remain pressurized between 80 and 140 PSI. Since most air tools operate in this range, it is ok for the compressor to maintain pressure in that range. You do not want to adjust the maximum pressure safety release valve as it could be extremely dangerous as certain components in the compressor may only be rated up to 140 PSI or slightly higher before they fail or blow apart.

Won't start -Porter Cable Cable 135 PSI, 60 Gal compressor


ARE THE POINTS BURNT IN THE PRESSURE SWITCH? DO YOU HAVE A LEVER ON THE SWITCH SET TO ON OR AUTO? IF YOU THINK ITS THE SWITCH JUST BYPASS IT AND TIE THE WIRES TOGETHER TO SEE IF IT RUNS. BEWARE YOU HAVE NO PRESSURE PROTECTION EXCEPT POP-OFF VALVE. MOST P.O.S. COMPRESSORS LIKE PORTER CABLE HAVE 3500 RPM MOTORS AND HAVE A THERMAL RELEIF BUTTON ON THEM. JUST PUSH TO RESET. MAKE SURE YOUR WIRNG OR DROPCORD IS LARGE ENOUGH GAUGE. SMALL GAUGE DROPCORDS KILL COMPRESSORS.
