It regulates the air compressor by controlling cut-in and cut-out pressure, typically between 100 and 120 PSI, to prevent over-pressurization and ensure consistent brake function. It should be replaced if you experience slow pressure buildup, frequent cycling, or fluctuating air pressure. The D-2 governor is a universal component with 1/8-inch NPT ports and is adjustable.
