The invention provides a cable tension adjusting valve, and belongs to the field of hydraulic devices. The cable tension adjusting valve comprises an outer valve body, an oil supplementing valve assembly and a load sensitive valve assembly. An oil supplementing cavity, a load-sensitive cavity, a high-pressure flow channel, an oil supplementing flow channel, an oil outlet flow channel and an oil inlet flow channel are arranged in the outer valve body, the oil supplementing cavity and the load-sensitive cavity are spaced, and the oil supplementing cavity, the high-pressure flow channel, the load-sensitive cavity, the oil inlet flow channel and the oil supplementing flow channel are sequentially communicated to form a loop. A first port of the high-pressure flow channel, a first port of the oil inlet flow channel and a first port of the oil outlet flow channel are located in the outer wall of the outer valve body, and a second port of the oil outlet flow channel communicates with the load sensitive cavity. The oil supplementing valve assembly is located in the oil supplementing cavity. A load sensitive valve assembly is located within the load sensitive chamber. The cable tension can be accurately controlled.
