DESCRIPTION
The Bendix
®
MV-3
™
dash control module is a two-button,
push-pull control valve housed in a single body which includes
a dual circuit supply valve and a check valve. The MV-3
™
valve can duplicate the functions of any existing two or three
valve push-pull system and has the advantages of reduced
plumbing.
The MV-3
™
valve body, plungers and spools are made out of
a non-metallic, non-corrosive material. All air connections
are at the back of the valve with the exception of the optional
auxiliary port as shown in Figure 1.
The MV-3
™
valve provides the following functions:
1 - Tractor Protection.
2 - Trailer Service Air Control.
3 - System Park.
4 - Trailer Park Only.
5 - Trailer Charge with Tractor Spring Brakes Applied (Tractor
Park Only).
