LTD. Analysis of invalidation of the two MOOG valves was carried out with the help of advanced apparatus and profound expertise in this area at Fudan University. Our research reveals that poor quality of the valve surface is the root cause for invalidation. A detailed description of the method used in analyzing the invalidation of electro hydraulic servo valve is presented in this article. This research demonstrates that academic institutes can play a significant role to solve engineering problems by leveraging their existing resources.
