Key Features & Benefits

This little guy basically controls the air flow to your trailer brakes. It has a rotating component inside – that's where the “rotary” part comes from – and it slides to direct air where it needs to go. It manages service, emergency, and spring brakes on the trailer. It essentially takes the signal from your tractor – trailer’s brake pedal and translates that into brake application on the trailer. It’s a key part of the whole air brake system, managing pressure and ensuring things happen in the right order. Think of it as the central command for your trailer brakes. It receives air pressure signals from the cab and then directs that air to the wheel cylinders or air chambers on the trailer. It’s positioned in the air line that runs between the tractor and the trailer. It’s what allows you to apply and release the trailer brakes independently of the tractor’s brakes, and it's crucial for things like parking and anti – lock braking systems if your trailer has them.

Symptoms, Risks & Replacements

It’s hugely important for safety, honestly. If this valve fails, you could lose your ability to control the trailer brakes, which is obviously a really dangerous situation. You’ll notice if it's failing because you might have trouble applying the trailer brakes smoothly, or you could have one or more brakes locking up. It acts like a shield protecting your ability to safely stop the entire combination. A faulty valve could also lead to the trailer brakes dragging, causing overheating and potentially a fire.
