To manually drain the valve, push the wire in the exhaust port
up and hold until the valve is drained. The valve has a die
cast aluminum body and cover.
Pressure Protection Valve
.
There are three pressure protection valves in the air system.
The purpose of the pressure protection valve (see
Figure 8-61) is to isolate one system from the other by
closing at a preset pressure. One valve isolates the primary
system from the secondary system, one valve isolates the
auxiliary system from the primary system, and the other
isolates the tire inflation system from the primary system.
The valve is a normally closed valve which can also be
referred to as a non-exhausting sequencing valve. The valve
has two ports: a supply port and a delivery port. The closing
pressure is 5.86 bar (85 psi) and opening pressure is about
1.00 to 1.40 bar (15 to 20 psi) higher than the closing
pressure. The valve is preset to the specified opening and
closing pressures.
Double Check Valve
There are three double check valves used in the air system.
The double check valve (see Figure 8-62) is used when a
function or component is controlled by either of two sources.
The higher of the two pressures is transmitted to the output
port.
Relay Valve
The purpose of the three relay valves (see Figure 8-63) is to
speed up application of the parking and service brakes. The
valve is remote mounted and delivers air to the brakes in
response to signals from the parking and foot brake control
