DESCRIPTION
The Bendix
®
 SRC-7000
 trailer spring brake valve is 
a reservoir-mounted trailer valve that can control up to 
six spring brake actuators during parking or emergency 
applications. It has the following capabilities:
•  Automatically applies trailer spring brakes in the event 
of a breakaway or trailer supply line failure.
•  Protects trailer reservoir(s) air pressure in the event of 
a breakaway or trailer supply line failure.
•  Does  not  allow  an  automatic  trailer  spring  brake 
application with air pressure loss in trailer reservoir(s).
•  Allows the trailer spring brakes to be applied and released 
repeatedly with a failed trailer reservoir(s):
•  Anti-compounding prevents an overriding service brake 
signal while the trailer supply line is at atmospheric 
pressure.
•  Does not allow service system charging if a failure occurs 
in the parking brake circuit.
•  Muffl
 er & snorkel capable.
