Enhancing driving safety and comfort with eCDV Valves for Active Damping
At Solero Technologies, we deliver advanced eCDV valves for active damping, enhancing vehicle safety, comfort, and handling in diverse driving and road conditions. As driving dynamics evolve, our innovative solutions cater to the latest and future vehicle generations. With increasing demand for precision, stability, and comfort, active damping systems play a crucial role in optimizing ride quality. Our high-performance damping technology continuously adapts in real-time, improving traction, comfort, and vehicle control.
Designed for modular integration, our customized damping solutions enable damper system manufacturers to accelerate development, reduce costs, and bring proven, cutting-edge technology to market faster.
Working principle
The External Continuous Damping Valve is a high-performance, electronically controlled valve designed for use in adaptive suspension systems. Mounted externally to the damper, it continuously adjusts damping forces in real time based on road conditions, driving style, and vehicle dynamics. By regulating the hydraulic fluid flow through an electromagnetic actuator, it enables seamless transitions between comfort and performance modes.
Ideal for premium vehicles, SUVs, and sports cars, this valve enhances ride comfort, handling precision, and overall driving safety. Its modular design allows for easy integration, making it a versatile solution for next-generation suspension systems.
