• Low cost – an economical alternative to our SR-5™ valve
model, with the same Bendix durability and performance.
• No corrosion – the SRC-7000 valve is constructed from
engineering grade plastic composite material tested for
extended service life under the harshest conditions.
• Combats contamination – our design features oversized
internal ports and seals specifi cally designed to perform
through more contaminants than any other valve on the
market.
• Simple design – the swivel fi t mounting tank fi tting prevents
over-torquing and possible damage during installation.

The Bendix® SR-5™ spring brake valve gives you a faster start
compared to other competitive systems.
The Industry Choice for over 27 years
The Bendix
• Rapid Apply and Release – ensure that parking brakes do not drag at
low system pressures.
• Durability – the robust relay valve design enables the SR-5™ relay valve
to have superior performance in the presence of air line contaminants
commonly found in trailer systems.
• Safety – with service air loss, the SR-5™ valve prevents automatic
application of the spring brakes and allows the application and release of
spring brakes, as required, to safely stop and park the vehicle.
• Anti-compounding – the SR-5™ valve’s anti-compounding feature provides
increased robustness and improved failure detection by audibly exhausting
air through the tractor protection valve at the back of the cab.
• Ease of installation – tank mounted, identical plumbing confi guration as
competitive valves.
