The Bendix

MV-1
™
modutrol assembly is an integrated air
control module designed for dash mounting in a truck/tractor.
The bodies for the modutrol assembly, as well as for the
"spool" inserts, are molded of a nonmetallic, noncorrosive
material. The assembly consists of three push-pull type
valves and two optional lever type valves. All valves utilize a
spool "insert," which can be replaced from the front of the
assembly without removal of the assembly or connecting
air lines.
The three push-pull type valves provide the following functions:
1. Tractor protection control.
VALVE A
VALVE B
VALVE C
VALVE D
2. Trailer service air supply.
3. System park.
4. Trailer park only.
5. Trailer recharge with tractor spring brakes applied.

spool "inserts." The functions of valves V-1 and V-2 are
essentially the same as the Bendix
Valve V-3 utilizes a spool "insert" consisting of two valves; a
nonautomatic push-pull function similar to that of the Bendix
