At KNR, we’ve developed and optimized our own nozzle-flapper-type servo valve, specifically for use on small hydraulic robots. It operates at a bandwidth of over 60Hz (special model 90Hz), and has its own controller, which allows for control of compliance, force, and displacement. Compared to imported products, this valve is economically priced, and we provide modeling information to help improve control performance. Using this valve and other components, we are leading the way in customizing robots for specific purposes.
