The 120v compressor on my 93 coach turns off between 90-100 psi and has no separate safety valve. If you know the brand of your compressor you may be able to find on the Internet the max pressure. My 93 coach has the governor set at 125 psi with the safety relief on the "supply" tank set at around 140psi.
