Precise damping control with DTS Valves for Active Suspension Systems
With DTS – Direct Controlled External Continuous Damping Valve (NO) Solero Technologies offers a high-performance valve designed for precise control over damping forces in active suspension systems. With an identical hydraulic and mechanical interface to the series design, this valve ensures seamless integration and delivers comparable functionality to standard products.
Engineered with Solero’s proprietary intellectual property and a cost-optimized design, the DTS valve combines high reliability, robust performance, and flexibility. It offers five variable defined cracking points, a wide temperature range, and compatibility with customer-specific PWM for dynamic damping control.
With more than 10 million units produced, the DTS valve demonstrates Solero’s extensive experience in delivering high-quality, efficient damping solutions that improve suspension performance, comfort, and vehicle handling.
Working principle
Dynamic control
The DTS Valve works by controlling the flow of hydraulic fluid through a damping system to adjust damping forces based on real-time input signals. It utilizes pulse-width modulation (PWM) to adjust the damping characteristics continuously, allowing for precise control over the suspension’s performance.
At its core, the valve responds to PWM signals (customer-specific), altering the flow rate and pressure within the system. The five variable defined cracking points ensure that the valve can precisely adjust damping force based on specific driving conditions, offering dynamic responses to varying road surfaces and vehicle loads.
Designed to operate in extreme conditions, the valve functions within a temperature range from -40°C to 120°C and can withstand pressures up to 250 bar. The Solero IP enables the valve to deliver reliable performance while remaining cost-efficient. With a low power consumption and optimized design, the DTS valve provides an ideal solution for active suspension systems that demand precise, continuous damping control.
