けたことを特徴とする油圧回路。 A hydraulic circuit in which a servo valve switched by an electric signal is interposed between a hydraulic source and a hydraulic actuator, and the direction of pressure oil sent from the hydraulic source is switched by the servo valve to drive the hydraulic actuator, A manual directional control valve capable of switching the direction of pressure oil from the hydraulic source is provided in parallel with the servo valve between the hydraulic source and the hydraulic actuator, and an electrical connection to the servo valve is provided on the downstream side of the servo valve. A hydraulic circuit comprising a block valve that hydraulically blocks a connection between a servo valve and a hydraulic actuator when a signal is cut off or when the servo valve does not operate normally.
