Facilities and economic development of plant facilities, the country"s underlying facilities to improve the energy efficiency of many studies are under way. In particular, ultra supercritical pressure power plants or under construction, stops the development of the critical pressure power plants and boilers that contributes main feed water control valve or main steam dump valve at the fluid cavitation and vibration control out of pipes and valves due to breakage and damage to parts of the plant raises a number of cases has caused them to stop the coup. In this study, we confirmed through the analysis of computation fluid dynamics and field demonstration test that in the control valve trim structure, "3-D Wave Trim" with the flow path of Z-axis fluid collision, XY-axis labyrinth and flexion type could dissipate the energy by fluid resistance, turn number, flow path area etc and result in pressure drop down.
