Disclosed is a servo valve module including two or more selectively operable servo valves and a hydraulic actuator utilizing the servo valve module. The present invention can use a conversion valve utilized by the servo valve module to choose an operating valve among the two or more servo valves. Accordingly, when an operating servo valve is malfunctioning or needs to be replaced, the valve can be inspected and replaced without having to stop the operation of an entire apparatus, thereby reducing the cost wasted due to the stopping of the apparatus. |
