Its dimensions are 204 x 138 x 170 mm. This valve is an OE specification part, engineered to provide a precise and durable solution for air brake control.

Key Features & Benefits

This valve basically controls the flow of compressed air in your air brake system. It’s electrically operated – that’s what the ‘solenoid’ part means – and it opens and closes to allow air into or out of the air bags or actuators that actually do the braking. The ‘Ecas’ part usually means it's part of an Electronic Control Air Suspension system, so it works with the computer controlling things. It manages things like leveling the vehicle and assisting with braking force. It's a pretty precise component. Think of it like a gatekeeper for the air that powers your brakes. The computer sends a signal, the solenoid opens the gate, and air flows where it needs to go. It’s not the brake itself, but it’s absolutely essential for the brakes to work properly, particularly if you have an electronically controlled suspension. It impacts ride height control too, keeping everything level.

Symptoms, Risks & Replacements

Well, without this valve working, your brakes won’t be able to apply correctly, or at all in some cases. You’ll notice if it's failing because your brakes might feel spongy, or you could have trouble maintaining ride height, or even experience a complete brake failure. It really acts like a shield, protecting the system and ensuring everything operates as it should. It’s a safety – critical component, so it’s definitely something you want to keep in good working order. You can find these online, places like Fixparts Online have a good selection, but getting a quality one is key.
