Abstract The influence of valve opening on optimization of a water supply pipe network system was studied by using Flowmaster software to improve the hydraulic performance of the network. The mode-ling process of basic components, such as pipeline, gate valve and valve opening controller, was provided, then several sets of model parameters were simulated and the variation of resistance factor in the system was analyzed and contrasted at different valve openings. A fluid pipeline system was taken as the study object, and the whole system was modeled firstly. Then the resistance factors of the gate valve and pipeline were optimized. Finally, the influence of valve openings on the pipeline resistance was explored according to different water supply conditions, and the optimum valve opening was obtained. The results show that when the water supply network system is under large and small flow operating conditions, respectively, the valve opening should be comprehensively adjusted based on user actual water demand, valve and pipeline resistance factors to appropriately reduce the hydraulic loss in the network and optimize the hydraulic performance of the system.
