Butterfly valves have been used to control the flow rate of various fluids in many industries because it have unique manageability compare to other valves. However, when a defect occurs due to the failure of the backlash of the power transmission part and the pin breakage of the butterfly valve due to the absence of the design capability of the valve, it is difficult to analyze the cause and maintain it. In this paper, a study was conducted to secure the reliability of the valve by performing structural analysis and analysis using a 3D model of the product to manufacture a high-quality valve.
