The PRV valve pops. is their a way to adjust the pressure switch to a lower setting. We have a Speedaire two stage compressor.

PRV lets go early
by: Bill

I suspect a contaminated PRV, John.

Tank empty and power off, pull the PRV and rinse it in solvent. Let dry. Reinstall. Close drain and start compressor. If the PRV lets go early again, replace the PRV.

It make no sense to reduce the standard pressure settings of your compressor.

If you insist in doing so, see the many pages on this site about pressure switches and how to adjust them.
