These components provide direct control over the air pressure within an air suspension system. Utilizing levers or knobs, they allow the operator to inflate or deflate air springs, thereby adjusting the vehicle’s ride height and suspension characteristics. For example, in custom vehicles or heavy-duty applications, operators might employ such devices to compensate for varying load weights or terrain conditions.
The capability to precisely manage air pressure offers numerous advantages. This includes improved load leveling, enhanced ride comfort, and increased ground clearance when needed. Historically, these systems offered a straightforward and reliable means of adjusting suspension settings before more complex electronic systems became prevalent. Their simplicity also makes them a viable option for applications where electronic control is either undesirable or impractical.
