Most of pressurized liquid pipelines are threatened by the hazards of a physical phenomenon that likely occurred in the hydraulic system when flow characteristic is rapidly changed. This change will make local energy imbalance which induced pressure wave travelling along the hydraulic system. Further, many devices are designed to control the hydraulic transients event. But, these devices still have incomplete performance because they dont be verified under different transient trigger conditions. In this paper, the performance of double controlled hydraulic system is verified by changing the transient trigger methods. Where, the double control of this system consisting of air vessel and HDPE forward configuration bypass. Moreover, four transients trigger scenarios are performed in this study and the performance of the hydraulic system for each scenario is investigated experimentally and numerically. Further, the experiments are revealed that the performance of hydraulic control system is highly affected by the way of the hydraulic transient is generated. Finally, the experimental and numerical results are well convergent by a total percentage is (92%).
