Case Review
This deep-drawn housing is the core body for an air suspension solenoid valve (damping valve). It's held to tight tolerances on the inner diameter and concentricity, and the visible surfaces get a zinc-nickel electroplated finish for corrosion resistance. This housing feeds into the ECAS (Electronically Controlled Air Suspension) solenoid valve and also serves as a balancing valve. With the growing demand for air suspension in new-energy vehicles, we're one of the first domestic shops to produce ECAS solenoid valve housings, and our parts fit most major OEM platforms. Several OEMs already buy this part from us. If you need it, we can run it to your print or refine the existing design for better manufacturability.
