Its job is to ensure that a minimum safe air pressure (around 70 PSI) is reached before allowing air to flow to non-essential or accessory circuits, such as air suspension or auxiliary equipment. This prevents a sudden loss of braking power if a failure occurs in a secondary system. Replace this valve if your air tank pressure drops faster than it should, or if air is leaking from the valve’s exhaust port, indicating a failed internal check or stuck piston.
