Abstract
The standard ISO 6358 is often used for describing flow rate of pneumatic valves. This standard uses sonic conductance and the critical pressure ratio to calculate mentioned flow rate. Different valves can be compared by these two parameters and an accurate mathematical model of flow rate can be created for an actual valve. The presented work is based on the measurements of the charge and the discharge of a tank through a valve. Downstream pressure, upstream pressure, temperature for both supply air and pressurized air inside the tank are monitored. The sonic conductance and the critical pressure ratio are obtained from this process as inverse models for two valves.
