is a hole drilled into the flat surface between the pressure protection valve and the body.

- Reservoir Nipple: 1/2" NPT
- With anti-compounding
The SR-5 is a trailer spring brake control valve. It mounts to a reservoir on the trailer and, like the SR-2 & 4,
it controls the trailer spring brakes. The SR-5 is similar to the SR-2 and SR-4 but it allows for simpler
trailer system plumbing while complying with the latest version of FMVSS 121 (Docket 90-3, Notice 4).
However, unlike the SR-2 and SR-4, the SR-5 controls trailer spring brake release using trailer Supply Line
pressure. Because dedicated or isolated reservoir pressure is no longer required by law for spring brake
release, the SR-5 system needs only a one reservoir for service volume on single axle trailers. Two
reservoirs are generally needed for 121 service volume requirements on tandem units. An integral anti-compound
feature is part of the SR-5.
Older trailers using the SR-4 can easily be upgraded to the SR-5 with a minimum of repiping.
