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.
