The 3/2-way valve supplies the high pressure air to ship engine for starting engine. In this paper, the high pressure 3/2 way valve for ship engine has the goal as reverse engineering by searching the fluid characteristic at this valve. The reverse engineering of 3/2-way valve is measured directly by Verier-calipers and is compared with 3D scanner. The fluid characteristic in this valve is used for a simulation method by ANSYS CFX 12.1. On the contrary, discs and the shaft are as the important components on numerical simulation by controlling the air flow at this valve. The fluid characteristics are seen to make high velocity and complicated vortex around the shaft. And the flow coefficient is calculated in order to apply for industrial field.
