The anti-compounding valve is the QR-1C. This is one I am using as part of the conversion on my 01. And that is just one of many anti-compounding valves. The text below was taken from the Bendix site.
The Bendix® QR-1C™ is a dual function valve. The valve’s
primary function is to serve the emergency side of a spring
brake actuator as a quick release valve. In addition, it
functions as an anti-compound device. The double check
valve prevents a service and emergency brake application
from occurring simultaneously.
My manual states that Eagle 05's used a E-6 treadle valve, here is a description of that and an E-10. I chose to use the E-6 valve. The E-10 is a taller valve and I don't have the room between the floor mount and the top of the steering gear mount bracket.
The E-6™ and E-10™ dual brake valves
are floor mounted, treadle operated type brake valves with
two separate supply and delivery circuits for service (primary)
and secondary braking, which provides the driver with
a graduated control for applying and releasing the vehicle
brakes.
The E-10™ dual brake valve is similar to the E-6™
dual brake valve except that a metal coil spring housed in
an upper body assembly replaces the rubber spring used in
the E-6™ valve. The use of a metal coil spring (and the upper
body assembly) provides greater treadle travel and, therefore,
provides the driver with a less sensitive "feel" when
making a brake application. The E-10™ dual brake valve is
generally used on buses, where smooth brake applications
contribute to passenger comfort.
I am very fortunate to have two air brake experts helping me with this conversion, they are very familiar with bus air brake DD-3's and Spring Brakes.
