Abstract: The moving element in a check valve assumes positions depending on flow which makes modeling more complicated than that of fixed geometry devices. Thus, it is necessary to determine the force ...

Abstract: The important time for a check valve is the short period during which flow decelerates. The characteristics of this period are not well defined. The investigation suggests the use of deceleration ...

Abstract: Since check valves are often installed and forgotten, some guidance is needed for their installation so that maintenance can be minimized and scheduled. A study of their behavior over a wide ...
