Question

Quizplus · Accepted Answer

When the lever of a pneumatic air suspension height control valve moves downward off horizontal, it typically signals that the vehicle's suspension is too high. To correct this, the valve allows some air to be exhausted from the air springs, lowering the vehicle to its proper ride height. This process does not involve charging more air to the springs, dumping all the air, or inflating the springs to chassis system pressure.
