Smart, stackable electromagnetic 2/2-way valves: unmatched flexibility, optimal cleaning!
Spearheading cleaner automotive innovations - crafting a precise and reliable cleaning system for Autonomous Vehicles Level 2+, 3, 4, 5
As autonomous vehicles gear up for enhanced cleaning systems, the need for efficient valves is becoming increasingly important. KENDRION responds to this development and introduces it's stackable electromagnetic 2/2-way valve concept - a smart solution hosting up to six valves on a single manifold. This design caters to OEMs and system designers, offering a seamless solution for pressure loaded sensor cleaning systems helping to keep LiDARs, sensors, cameras, screens and head-lamps, clean and reliable. Our valves distribute cleaning media to the different cleaning system’s nozzles with optimal flowrate at given input pressure. This leads to an increased cleaning efficiency with minimized power consumption. With the ability to switch pressures up to 5 bar, our valve concept can quickly provide precise cleaning processes in air and water systems. In addition, our smart system efficiently controls BLDC motors for central water pump or air compressor operations.
Our valve setup meets rigorous automotive safety standards, boasting an IP65 or higher rating. The benefits are clear -flexibility and economy with easy replacement of individual valves, effortless installation and connectivity with quick-connector compatibility, and an all-round sustainability approach, minimizing waste and energy consumption.
Flexibility and economy: The platform's adaptability stands out as it accommodates from one to six valves per manifold, providing unparalleled flexibility, ensuring efficient power consumption.
Effortless installation and connectivity: With quick-connector compatibility for both hydraulic and pneumatic configurations, the system guarantees seamless integration and streamlined operation.
Sustainability all-round: The stacking concept allows for more compact integration, reduced weight, and fewer wires. And to conserve resources, each valve is individually replaceable when the ECU signals the end of its life or in the event of damage or failure, eliminating the need to replace the entire manifold.
