Key Features & Benefits

This valve basically takes a low – pressure signal from your brake pedal and boosts it into a higher pressure to operate the air brakes on your trailer or larger vehicles. It’s like a little amplifier for the air pressure. It opens and closes to control the flow of air, allowing air to pass when you hit the brakes, and cutting it off when you let up. It also has a quick release feature, meaning when you release the brake pedal, it vents air quickly, helping the brakes disengage faster. It sits in the air brake line between your tractor protection valve and the emergency line going to the trailer. It’s a crucial part of how you actually apply the trailer brakes. Without it, you wouldn’t have enough force to reliably activate those trailer brakes, especially on larger loads. It doesn’t create the air pressure, it just manages and boosts what you already have.

Symptoms, Risks & Replacements

Think of it like a shield for your whole air brake system. If this valve fails, it can prevent the trailer brakes from applying fully, or even at all. You’ll notice if it’s going bad because your trailer brakes might feel weak, slow to respond, or you might have trouble getting them to fully release. It’s a safety item, plain and simple. You want these working right. We carry a good selection of these – you can even find a simple relay valve like this on Fixparts Online if you want to take a look at the options and prices. It’s a relatively inexpensive part to replace, and it's much better to address it before it becomes a serious problem on the road.
