Product Description
TOKYO KEIKI E244-010036-13 is a two-stage electro-hydraulic servo valve from Tokyo Keiki (Tokimec) E244 series. It adopts nozzle-flapper construction with torque motor drive and built-in LVDT spool position feedback. It accepts 4–20 mA analog command signal to precisely regulate hydraulic flow and direction. Featuring fast response, high repeatability and low hysteresis, it offers good vibration resistance and moderate contamination tolerance. It is widely used for high-precision closed-loop position control of turbine actuators and anti-surge hydraulic valves, a common Japanese servo component for turbomachinery hydraulic control packages.
