• This study has clarified the characteristics of the fiat disk valves with a rounded inlet corner of clearance. In the range of small lifts in which water is used as the experimental fluid, the head distributions at the inlet pipe are almost constant. And there is no difference between the head at the valve and that at the valve seat. On the other hand in the range of large lifts in which #30 motor oil is used as the experimental fluid, the head distributions at the inlet pipe depend on the size of rounded inlet clearance. And a decrease in head at the inlet pipe is almost equal to the additional loss of head. It is clear that the additional loss of head occurs at the entrance part which is the area between the center of inlet pipe and the inlet of clearance.
