VAM(®) AIR ADDUCTION VALVE

The “VAM” (Multifunctional Automatic Air Valve) installed in a water pipeline enables both the expulsion of air in the pipe filling phase and free entry of air in the emptying phase.

It is especially suitable for mounting in areas downstream of dam intake and outlet valves, filling the spaces in the valve shut-off devices where there is a vacuum with air during partial opening, so preventing cavitation phenomena. (VAM technical sheet)
