The invention discloses a hydraulic circuit for a hydraulic valve durability test and a test method. The hydraulic circuit comprises a plurality of hydraulic test circuit groups and a plurality of tested balance valves connected with the hydraulic test circuit groups, in the loop, pressure sensors are installed between a first energy accumulator and a first electromagnetic valve, between a second energy accumulator and a second electromagnetic valve, between the first electromagnetic valve and a port A of a first tested balance valve, between ports B of the two tested balance valves, between the second electromagnetic valve and a port C of a second tested balance valve, and between a port C of the first tested balance valve and a port A of the second tested balance valve. The input end of the controller is connected with each pressure sensor to receive the pressure value; the output end of the controller is connected with the first hydraulic pump, the second hydraulic pump, the first electromagnetic valve and
