It use the Float down with the surface of the valve lift of the use of force, opening and closing the linkage exhaust. When the gas is collected in the valve , due to air pressure, inner surface of value move down, thus resulting the float reduced.when the float down to the lowest .the linkage level system will open the value gate.
