• This study has clarified the relations between the coefficient of additional head loss and valve lifts, and the relations between the pressure distribution and valve lifts. We assume that the total head (head of valve center) is equal to the summation of frictional loss of head in the parallel plate, velocity head at outlet and additional loss of head. For those purpose we have experimented on many valves under the condition of various valve lifts and three fluids; water, kerosene and motor oil. There three fluids are used to expand the equivalent Reynolds number range. The conclusion is that the coefficient of additional head loss in nearly zero but a positive value and gets larger in proportion as valve lifts increase at the same equivalent Reynolds number in the range of the experiments. The pressure distribution at the inlet of valves does not show the same tendency as each valve and it depends on valve lifts.
