The pressure differential is directly related to the flow of air (SCFM) through the valve. When the pressure differential is within the operating limits - below the cutoff flow - of the unit, the force on the valve exerted by the spring is greater than that caused by the pressure differential. The valve remains open and normal operation continues. When the pressure differential is above the cutoff limit, the force on the valve exerted by the pressure differential is greater than the force exerted by the spring, and the valve closes. After the repair is made, normal operation is automatically enabled when pressure across the valve equalizes through the bleeder hole.The valve spring size can be specified by determining the air flow during normal operation and by estimating the air flow if a failure or rupture occurs.
