Key Features & Benefits

This valve basically directs airflow in an air brake system. Think of it like a traffic controller for air. It has three ports – one in, two out – and it switches the air flow between those two outputs depending on the signal it gets. It can open one path while closing another, or even send air to both at once, depending on how it's set up. It controls things like the spring brakes and the service brakes – really the core functions of stopping the vehicle. It’s a key component in how your air brakes work. It's often used to apply and release the spring brakes – those emergency brakes that kick in if you lose air pressure – and also to control the normal service brakes when you push the pedal. It works alongside the brake pedal valve and other components to create the proper air pressure to the brake chambers. A lot of larger trucks and trailers use these, especially for the trailer's spring brakes.

Symptoms, Risks & Replacements

Without a good 3 – way valve, your brakes just won't function reliably. If it fails, you might lose the ability to apply your spring brakes, or it could prevent the service brakes from releasing properly – a serious safety hazard. You’ll notice if it's going bad because you might have trouble applying the emergency brake, or the trailer brakes might drag. It acts like a shield, making sure your brakes respond when you need them to. If you're doing air brake work, it's a part you definitely want to inspect.
