VANNAIR triple function air valve Operation Description “Vannair” double orifice air valves are built according to an original compact design, with or without isolating valve. They are made of two floats mechanically free, operating in a single chamber body, aerodynamically shaped. One float is a ball fully covered with elastomer, the other is a disc in which are inserted two O-rings in a concentric way. Movements of the floats are guided in up and down direction. The floating ball ensure the shut-off of the small orifice, whereas the floating disc ensure the shut-off of the bonnet large orifices....
