10. Standard Air Control
System Installation
The following is a typical air system installation and should
be plumbed as illustrated
(Figure 13)
. Optional air control
systems are available. Contact SAF-HOLLAND applications
department to discuss your particular needs.
The air control system of the CBX/CB suspensions use air drawn
from the tractor air system to pressurize the suspension’s air
springs. The suspension, working with the air control system,
provides optimum suspension performance only when all air
control system components are installed and operating properly.
IMPORTANT:
Make certain that all air lines and valves
are free from obstruction through the full
operational range of the suspension.
IMPORTANT:
A pressure protection valve (PPV) MUST
be attached to the air reservoir in order to
maintain proper air pressure
(Figure 13)
.
IMPORTANT:
The air pressure protection valve maintains
safe brake pressure. Approximately 85 psig
(5.9 bars) opens the valve, and 65 psig
(4.5 bars) closes the valve.
NOTE:
When installing the pressure protection valve,
use a drop of oil or Loctite
®
to lubricate threaded
connections. DO NOT use a pipe compound or
teflon tape as they may clog the valve.
A height control valve (HCV) is used to regulate the air
pressure required for varying load capacities
(Figure 13)
