Key Features & Benefits

This valve basically controls the air pressure going to the airbags on your vehicle – specifically, the ones that handle cabin tilt. It takes input from the vehicle’s sensors and adjusts the air flowing to those airbags to keep the cabin level, even when you're driving on uneven ground. It’s an electro – pneumatic part, meaning it uses both electricity and compressed air to work. It regulates the airflow, telling the airbags to inflate or deflate as needed. Think of it as the brain behind your cabin leveling system. It's part of a network that includes the airbags themselves, the height sensors, and the air compressor. The height sensors send signals to this valve, letting it know if the cabin is tilting. The valve then reacts, sending air to the airbags to correct the tilt. It’s mostly found on vehicles that have a cab tilting function, like some trucks and RVs.

Symptoms, Risks & Replacements

If this valve fails, you’ll notice if your cabin isn’t leveling properly. It might stay tilted, or constantly be trying to adjust but failing. That’s not just uncomfortable, it can mess with handling and stability, especially if you’re operating heavy equipment or traveling on rough terrain. Plus, constantly fighting to maintain level can put extra strain on the air suspension system and potentially damage other components. We carry these pretty regularly – you can often find a good replacement at Fixparts Online if you’re looking. Replacing it gets things back to riding smoothly and safely.
