In this study, numerical simulation of the closed die hot forging process of CuZn40Pb2 brass alloy water valve cover was analyzed. During the hot forging process of the brass alloy water valve cover in a conventional single stroke forging press, a number of defects occur in the formation of the material geometry. The main factors affecting these defects are cylindrical billet and die temperature. Finite element simulations including geometry, filling sequence and force were performed with Deform 3D software and the effect of temperature was optimized. However, during the experiment, it was observed that when the brass alloy water valve cover is forged in a conventional press, the coefficient of friction, which decreases with the use of lubricant, also significantly affects the flow behavior of the material. Through further analysis of the experimental process and finite element simulation results, the causes of die and valve cover defects were discovered. The results of stress and strain values obtained with the support of finite element simulation showed that temperature and friction coefficient have an effect on forging defects. The experimental results were found to be in agreement with the finite element simulation results.
