Key Features & Benefits

Basically, this valve controls airflow in your air brake system. The “3/2 way” part just tells you how it controls it. It has three ports – one for pressure in, one for pressure out, and one that vents to the atmosphere. It switches between two positions – either allowing air to flow between the inlet and outlet, or blocking the flow and venting the pressure. It’s electrically operated, so when it gets a signal from the system, it either opens or closes that airflow. You’ll find these used in a lot of different parts of an air brake system. Things like controlling the operation of air brakes themselves, the parking brake, even the air suspension on some vehicles. It’s a pretty common component for directing air where it needs to go to activate those systems. Think of it like a gatekeeper for the air.

Symptoms, Risks & Replacements

Well, if this valve fails, whatever system it controls won't work right. You'll notice if it's related to your brakes – you might have trouble applying the parking brake, or even have issues with your service brakes holding properly. It’s a safety – critical part, because it directly impacts how well your vehicle can stop. It acts like a shield, preventing air from going where it shouldn't, and letting it through when it needs to. We carry a good selection of these, and you can often find a great price on a replacement at Fixparts Online if you’re looking. It's definitely something you want to keep in good working order.
