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 advantage of reduced plumbing.
The MV-3
®
module body, plungers and spools are
made out of a non-metallic, non-corrosive material.
All air connections are at the back of the module with
the exception of the optional auxiliary port.

The MV-3
®
dash control module combines the
functions of a PP-1
®
control valve and a PP-7
trailer
supply valve together into a unifi ed device.
Trailer Control (TC) valves are hand-operated,
graduated control valves. The most common use of
trailer control valves is for independent control of trailer
service brakes, however, the valve can be used for
any application where graduated application pressure
is required.
These valves use a cam and spring mechanism to
control delivery air pressure and are available with
several different styles of body, clamp and handles.
Some models are available with self-returning handles.
Trailer control valves are often used to hold the
vehicle while the vehicle’s clutch and accelerator are
co-ordinated. The trailer control valve should never
be used for parking.
