Location

The AIRmatic valve unit is a component of the AIRmatic compressor unit, which is located on a bracket behind the right bumper.

Task

The four level valves LR, RR, LF, RF serve to adjust the vehicle level.

P: To AIRmatic compressor unit

SP: To central reservoir

Function

If one of the level valves is actuated, air can be delivered into the corresponding bellows via the compressor and/or the central air reservoir (lifting vehicle). On the other hand, if the release valve is actuated when a level valve is actuated (with compressor switched off), air can escape from the bellows and the vehicle level is lowered.
