3Z182 valve flutters while compressor is on?

Speedaire compressor Model Number: 3Z182 (Photo: www.weiku.com)
i HAVE A SPEEDAIRE 3Z182 COMPRESSOR THAT WAS POPPING OFF THE 70 PSI VALVE ON THE SIDE. WE REPLACED IT AND THE SAME THING HAPPENS. IT STILL BUILDS PRESSURE AND SHUTS OFF WHEN FULL.I WAS WONDERING IF THAT VALVE ON THE FRONT OF THE COMPRESSOR HAS ANYTHING TO DO WITH IT.
Sorry chum, I don't know what you mean by a "POPPING OFF THE 70 PSI VALVE ON THE SIDE"?
This is a twin cylinder air compressor. Are you, perhaps, talking about the PRV between the cylinders? If that is the case, based on what you write, it isn't the PRV that is the problem, but likely the valve inside the second cylinder where the line between the two enters. That is an intake valve, and if it is compromised, back pressure in the line from the first cylinder may cause the PRV to pop off.
Can you post a closer photo of the Speedaire 3Z182 valve you are referring to? You may need to open a new thread to get the photo-upload window.
What is value of Speedaire Air Compressor Model 3Z323C?
by Chris DiPaola

I have a used Speedaire compressor model 3Z32C. I can't find it listed anywhere. Would you know about how much it is worth? It is in good condition.
Chris, there are so many models of so many compressors, no way I can give you details of any one from a model number.
Second, I searched too, and cannot find any info on your Speedaire 3Z32C compressor. Not knowing what its motor HP or the tank size really limits even an educated guess. :-)
If it were me, I would go to the compressor store and have a look at the prices for a new compressor of similar size and power supply.
If yours is in as good a condition as you state, what would be the value? Maybe 1/3 of the new price?
I know that most DIY air compressors of today are so low priced that I expect I'd pay $150 for new with a warranty over a used one of the same make for $50 unless it ran really, really good.

4b236b pump is on until it opens PRV
by pfc H

so the pumpwill stay on past the desired pressure.
that in turn kicks out the pressure releife valve.
so what is going on and how do i fix it so my compressor is ready for use all of the time and i dont have to shut it off at the breaker when I get some pressure in it just to use it for a bit?
( sorry about any errors in spelling and that this key board is wise beyond its years)i also want to say its a 4b236b compressor
Howdy... I'd like to say that I'm wise beyond my years too, but no, I'm just old!
Typically your compressor problem would be cause by a failed pressure switch. When the tank pressure reaches the normal cut out pressure setting, it's supposed to trip open, and cut the power to the motor.
You also don't have to shut off the compressor, as long as you realize that if you have a leak in a fitting then periodically the compressor will start on it's own when enough air has leaked out. Mine started up in the middle of the night... once! The boss was not impressed. Now I shut it off by pulling the power cord.

When the motor starts the conduit will shake and then the breaker pops.
Line run is approximatley 150' of 10 Gauge wire. It is on a 30 Amp breaker.
Electrical company came in and changed a part on the motor so it would switch from capacitor start to the hard wire line. That has helped but the condiut still shakes during start up.
The motor runs at 12 Amps during the run.
Any ideas would be appriciated.
