In order to guarantee the improvement of the whole performance for new type rotating ball valve with double direction metal sealing, a multidisciplinary design optimization (MDO) model was established based on objective function such as sealing preformance, mass, resistance performance for shock and flow resistance coefficient. Based on coupled effect between each subject, a new type rotating ball valve was designed by using MDO based on self-adaptive chaotic optimization algorithm. The results show that for new type rotation ball valve with double direction metal sealing, leakage ratio reduces 60.0%, mass reduces 2.15%, resistance performance for shock reduces 37.6%, and the flow resistance coefficient reduces 37.6%. The flow adjustment capacity is also improved after optimized.
