Integrated swivel functionPressure protection valves (PPV) insure that the air brakes, which are supplied from the primary reservoir, always have adequate pressure to function normally. This is a normally closed pressure sensing valve which allows air to flow freely in both directions as long as the upstream (primary) reservoir pressure is above the set point of the valve. Typical set points range from 55±10psi to 85±10psi. If a down stream failure occurs or during start up, the primary tank pressure may drop, thus causing the PPV outlet to shut off, in order to maintain the primary reservoir pressure.
