The closing of a springless flapper valve was investigated in order to gain a better understanding of the transient behavior of the valve. An experimental investigation included simultaneous measurement of pressure and flapper velocity. An analytical investigation included the development of a model to predict the closing of the flapper valve. The flapper closing was experimentally determined to require from 18 to 24 percent of a cycle, and the model predictions were in good agreement with experimental data for the flapper closing time. The present study should be a useful contribution to future modeling of flapper valves and other springless valves.
