(3) The regulated air control provides an
cushioned ride through varying load conditions. A valve
and filter assembly is installed in the line at the air brake
reservoir. These components maintain safe air brake
pressure and clean air.
(4) Sage air brake pressure of 65 psi is
automatically maintained by brake protection valve in the
event of air loss due to a failure in the air system.
(5) The air suspension is designed to operate
at a specific ride height. Height control valves (fig. 4-41)
are used to maintain the proper axle-to-frame
relationship necessary to regulate ride height. The
valves automatically regulate air to or from air springs.
