The 6670_AM ECAS-Solenoid Valve - CVs by Wabco is a critical component within commercial vehicle air brake systems, specifically designed for electronically controlled air suspension (ECAS) applications. This valve precisely controls the airflow to the air springs, enabling height control and contributing to a stable and comfortable ride. With a manufacturer part number of 4728900510, this solenoid valve features air cooling, a TYCO HDSCS 4 x 2.8 CODING A electrical connection, and is rated for a maximum operating pressure of 20.0 bar. It mounts using 3x Ø 8 mm fixings and boasts multi nominal diameters of 11.3 / 8.0 / 4.0 mm, with port threads of M22 x 1.5 JED - 388-4. This valve is built to OE specification and operates within a temperature range of -40°C to +80°C at 24 V with a rated current of 320 mA. Its robust design, featuring protection class IP 6K9K, ensures reliable performance in harsh environments, while its integrated silencer minimizes noise. The valve's dimensions are 225 x 65 x 210 mm.

Key Features & Benefits

This valve basically controls the air flow to your vehicle’s ECAS – that’s your Electronic Controlled Air Suspension system. It opens and closes to let air into the air springs – those big rubber bags that actually support the weight of your vehicle – and releases it when needed. It’s an electrically operated valve, so the vehicle's computer tells it when to activate. It has several circuits inside it – each controlling a different part of the suspension, like ride height at each wheel. So it’s not just one thing it does, it’s a multi – function controller for your air suspension. Think of it as the brain telling the suspension what to do. The computer decides if you need a softer ride, a higher ride for off – road, or to level things out when you have a heavy load. It sends a signal to this solenoid valve, which then directs the air to the appropriate air springs. It maintains a smooth, level ride and handles changes in weight and road conditions. It's a critical piece of the whole system – without it working correctly, your air suspension won’t function as it should.

Symptoms, Risks & Replacements

If this valve fails, you’ll likely notice it pretty quickly. You might see your vehicle sitting unevenly, or the suspension could be constantly trying to adjust itself. It could cause a really rough ride, and in some cases, the suspension might even completely deflate. Ignoring it can lead to further damage to other parts of the air suspension system – things like the air springs themselves, or the compressor. It's a relatively small part, but it has a big impact on your vehicle’s comfort and handling. We carry these at Fixparts Online, and you can find a good selection to get you back on the road.
