Pilot Exhaust Valve

The exhaust valve operates when the pilot exhaust valve is opened, allowing air to be exhausted quickly.

The pilot exhaust valve is connected to the air delivery gallery, downstream of the air drier. The pilot valve, when opened, operates the slave exhaust valve, allowing air to exhaust the system.

When the solenoid is energized, pilot air moves the slave exhaust valve plunger. The exhaust valve plunger allows the pressurized air from the air suspension system to pass through the air drier to the atmosphere.
