DESCRIPTION

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.

Reference Figs. 1 & 5, valves V-1 and V-2 utilize identical

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
