The valve should perform the following functions.

1. Evacuation of large quantities of air during the filling.The kinetic air/vacuum valves are specially designed so that the flow of air in evacuations reaches high velocity ( speed of sound) without the Buoy ascending for the effect of the current and stopping any premature closings until the evacuation is complete.
3. Admission of large quantities of air during the emptying and draining.
