An aircraft hydraulic valve includes a housing, a check valve, a valve opening component, and an auxiliary hydraulic pressure supply mechanism. The housing includes a first port communicated with a first chamber of a hydraulic actuator, a second port communicated with a switch valve bypass-communicating a second chamber of the hydraulic actuator with the first chamber, and an oil channel connecting the first and second ports. The check valve interrupts oil flow from the first port to the second port. The valve opening component is configured to open the check valve with pilot pressure supplied from the second chamber. The auxiliary hydraulic pressure supply mechanism obtains hydraulic pressure, for opening the check valve, from a closed hydraulic pressure section, which is defined in the oil channel between the check valve and the first port.
