Key Features & Benefits

This little valve basically controls the airflow in your air brake system. It directs air to different areas, specifically when you’re applying and releasing the brakes, or when you’re doing things like parking. It has multiple ports, and it switches the air flow between those ports – think of it like a railroad switch directing a train down different tracks. It’s a pretty precise operation. It's a key component in how your trailer spring brakes operate. It's responsible for applying and releasing those spring brakes. It gets signals from the tractor protection valve and other components, and based on those signals, it opens or closes pathways for the compressed air. It essentially allows air into and out of the brake chambers, which then activates or deactivates the brakes.

Symptoms, Risks & Replacements

It’s super important for safety. If this thing fails, your spring brakes can apply unexpectedly, or worse, not apply when you need them. You’ll notice if it’s going bad – things like erratic brake performance, brakes dragging, or the trailer trying to lock up. It acts like a shield, preventing unintended brake applications, and making sure everything functions as it should. You can find replacements pretty easily, Fixparts Online carries a good selection of these, and getting a new one is a lot cheaper than dealing with a brake failure on the road. It’s a critical safety component, so it's best to replace it at the first sign of trouble.
