Level Control Solenoid Valve: Description and Operation

Fig. 3 Exhaust solenoid

    The exhaust solenoid, Fig. 3, is located in the compressor head assembly and performs two functions. First, the exhaust solenoid exhausts air from the
system when energized and is controlled by the electronic height sensor. Second, the exhaust solenoid acts as a blow-off valve to limit the maximum
output pressure of the air compressor.
