DESCRIPTION

The AR-1

™

antilock relay valve (Figure 1) is a specialized

service brake relay valve. It is essentially an R-14

relay

valve with a special cover that permits direct attachment

of an antilock controller. When combined with an antilock

controller the resulting assembly is referred to as an

antilock relay controller. For example, when the AR-1

™

antilock relay valve is combined with the EC-30

™

tractor

antilock controller the resulting assembly is referred to as a

CR-30

™

antilock relay controller. While intended for use on

antilock equipped vehicles, the AR-1

™

antilock relay valve

functions solely as a service brake relay and contains no

electronics of its own.

In an air brake system, the AR-1

™

valve serves as a

relay station to speed the application and release of

the service brakes. The valve is normally mounted in

proximity to the service actuators it serves. A mounting

bracket furnished with the valve permits either frame or

cross member mounting. All air connections on the AR-1

™

valve are identiﬁ ed with cast, embossed letters for ease of

installation. The letter identiﬁ cation and air line connections

are shown below for reference.
