Robot

KNR Systems provides hydraulic robotic arms, standard mobile robots (robot arm platforms), hydraulic components, and robotic solutions based on its unrivaled hydraulic robot technology.

KSV (KNR Servo Valve) Series

The KSV Series servo valves deliver high performance with a control flow rate of 6.5 LPM at a pressure differential of 70 bar, and internal leakage maintained below 0.7 LPM. Equipped with our proprietary controller, they enable precise position, force, and compliance control. As one of the world’s top-tier servo valves, the KSV Series is offered at a competitive price point and provides product-specific control data. Customizable for robotic applications, it plays a key role in advancing the adoption of hydraulic robotic systems.
Our technologies have been validated through deployment in platforms operating in inaccessible environments such as underwater, nuclear, and high-temperature conditions. We are also continuously conducting R&D to develop high-response servo valves, further enhancing performance in extreme applications.

General users can easily integrate the valve into their applications by connecting it to the dedicated HAC controller, enabling convenient setup similar to that of a servo motor. Each servo valve is supplied with measured dynamic response curves, helping developers construct accurate dynamic models without additional testing. Optional dynamic characteristics at specific pressures are also available to further reduce application complexity. For expert users, customized options such as underlap, overlap, and internal leakage adjustment are supported—ensuring valve configurations are purpose-built to optimize full system performance.


While compact servo valves are generally associated with high costs and custom-made options are often considered prohibitively expensive, our company offers optimized development for specialized configurations at a highly competitive price point.
