Purpose: Generally, the operating period of existing butterfly valves is 3 to 6 months, with continuous maintenance and replacement. It is necessary to develop a butterfly valve with high performance that increases the facility''s efficiency and water treatment capacity and ensures reliability that it can be used even in an adverse vibrating environment. Methods: This study investigates the structural safety of the new valve with the conventional valve through structural analysis. Furthermore, the cavitation occurrence and flowability are investigated based on flow analysis according to the valve''s opening rate. Results: When comparing the existing model with the new model by performing structural and flow analysis, it was found that the structural stability, improved flowability, and the degree of cavitation were reduced effectively. Conclusion: Based on these results, applying the proposed design can efficiently reduce the overseas dependence of the industry of domestic butterfly valves and can also be applied for other developing related products and industries.
