摘要：Valves for hydro power projects are installed for safety, maintenance, and shut-off, as well as for flowand pressure regulation. A Butterfly valve is a type of flow control device, which is widely used to regulate a fluidflowing through a section of pipe. This type of valve is mainly used as safety valve, turbine inlet valve, and pump valvefor low to medium design pressures. They are operated by oil hydraulic systems for opening and closing or by closingweight and hydraulic pressure for opening. For turbine inlet valves, oil pressure can also be taken from the governorhydraulic oil system. The sealing system is of flexible, adjustable rubber/metal type to reduce leakage to a minimum.Water flow through the valve is possible in both directions.The main objective of this thesis work is to analyses theoption of fabricated variant for door & body in place of casted, reduction in the material of valve body & door bystructural design & FEM analysis & optimization in the material of valve component.The 3D modelling to be performsfor butterfly valve by using CAD software. Further the stress & displacement FEM analysis of the butterfly valve to beperformed by using ANSYS tool to evaluate the optimized result.
