Notes:
The welding process, a conventional production method of gate valves, has advantagessuch as light weight, but it also has disadvantages such high production price. However, the forgingprocess, has economic merits and mass production capability. The main focus of this paper is theoptimization of the preform in the forging process. This paper proposes an optimal design of thepreform to improve the mechanical efficiency of the gate valve made by the forging method. Thedesign of the preform is optimized by the use of the real response model to the Kriging model bycomputer simulation. Also, the optimized results were used to verify the response model. Theverified response model confirmed the usefulness and reliability of the Kriging method in optimumstructural design of preform achieved by finite element analysis and Kriging equations
