FIGURE 2 - TYPICAL AT-1DC
The ATR-1DC
™
valve is part of the R-12
™
which includes the R-12
valves. The internal components of the relay portion of all of
these valves are similar and in many cases interchangeable
™
with the R-12
valve and therefore the same basic
components are used to service all of them. The ATR-1DC
valve is available with various crack pressures to
accommodate specific applications, however the standard
is 4 psi, achieved without any added spring.

OPERATION
GENERAL
While the ATR-1DC
its true function is that of an air brake relay valve. Because
the ATR-1DC
™
control function, the following description of operation
describes its operation as a relay valve and its function in
the traction control system. The full operation of the
antilock system and separate antilock components and their
operation is not addressed in this publication. For a
description of antilock operation, refer to the appropriate
Service Data Sheet covering the electronic controller used
with the ATR-1DC
electronic controller, or SD-13-4788 for the EC-17
controller). Other useful information on antilock system
components may be downloaded from www.bendix.com. For
example: SD-13-4793 (M-21
