A numerical analysis for cavitation increase or decrease according to changes of cage holes size of globe valve has been performed. The numerical analysis has been made by using the SC/tetra code for solving the 3 dimension, unsteady, compress and turbulence flow inside the globe valve. Numerical simulations were performed at 30%, 50% and 100% of the valve openings and computational results for the ET cage type has been confirmed with experiment data by validation. The new cage forms have been made as 1/5D, 1/10D and 1/12D of valve size for each holes. 1/10d and 1/12d of hole size were compared with ET type and it is confirming that reducing the cavitation by comparing with pressure, maximum velocity and σ at 30% valve opening
