PRV pops every 1/2 second until compress turns off.

Hello, my tank which max at 175 psi, will run and shut off normally, except PRV at the start of intercooler pops air every 1/2 second or so until the compressor hits 175 psi.

The PRV is new with correct spec spring.

First I thought it was the oil that ran a little low, but that wasn't the problem.

Please help.

Thank you very much!

Mike, is your air compressor a two stage one, with the second cylinder increasing the pressure of the air going into the tank?

That being the case, you may want to check out the intake valve on the secondary pump cylinder.

Cheers,

Bill

Hi Bill, thank you for the reply.

Yes, it's 2 stage 7.5 HP unit.

The intake valve on the secondary pump cylinder as you've mentioned is where the air goes in from the intercooler?

Believe so. Check the flow path from cylinder one, to cooler, and then to cylinder two. The valve inside the head where the line reaches cylinder two is the possible culprit.
