PRV blows off on second air compressor
by QT Electrical Services LLC
We have a two three phase air compressors connected to two storage tanks at a body paint shop.
The problem we are experiencing is that as soon as both air compressors turn on to fill up the storage tanks the PRV goes off in a (DEVAIR COMPRESSOR THE CLIENT PURCHASED USED ABOUT 5 MONTHS AGO)
Model number VAVC-5000
Serial #35343 MD
175PSI MAX Pressure
Both compressors are being controlled by only one pressure control switch that way they can both operate simultaneously.
Like I said it takes about 10 second for the PRV to open in this new air compressor when both of them kick on.
There is one valve that was installed on the 3/4" pipe going from this compressor and Teeing into the main line that leads to the second compressor and two storage tanks that seems to not be working. It does not open or close. I will be replacing that first do you thing this valve can be stuck open mid way and its blocking the air flow from the VAVC -5000 compressor causing a buildup in pressure therefor activating the PRV rated at 200 psi???
Thanks in advance.
