Glad you got the right info from THE MAN HIMSELF! The RAW regs belleville washers pressure is compressed by a spring, so yes, that's how these regs work.Well I called Martin, and found out my reg. pressure was to low. Adjusted the regulator and all is well with my RAW. I replaced the reg. Orings awhile back but never touched to reg. Adjustment. Martin set it for me a few years ago, when he tuned and serviced it, but I guess as time goes by the beveled washers need to be compressed slightly to keep it where it needs to be ?
