A study was conducted to obtain fundamental flow characteristics for a practical spool valve whose inlet and outlet port position was set at 90°angle. Particularly in the present investigation two different geometric configurations of spool were examined. One spool has rectangular notches and another spool has no notch. Experiments were carried out to obtain basic flow and pressure relationship. By examining experimental data with numerical results, it was found that numerical results predicted the flow and pressure relationship very well, modeling approximate edge configuration on the spool and body. Various flow characteristics also were verified based on flow parameters of the spool valves.
