An armature assembly for an electro-hydraulic pressure servo valve comprises an armature, a stop lever, an elastic tube, a feedback rod and a steel ball. The armature sleeves the upper end of the stop lever; the lower end of the stop lever penetrates through a center hole of the elastic pipe. A connecting plate at the upper end of the elastic tube is fixedly connected with the lower surface of the armature; the upper end of the feedback rod is mounted in a feedback rod mounting hole in the end face of the stop lever working section; a steel ball is installed on the lower end face of the feedback rod. The area of the top disc of the elastic pipe is increased, the installation technology is improved, and damage to the elastic pipe is effectively reduced. The feedback rod additionally arranged on the basis of the prior art and a valve element in the electro-hydraulic pressure servo valve support each other, the stability of the armature assembly in the complex flow field environment is guaranteed, the capacity o
