Abstract
This work aims to study in detail the methods of experimental characterization of air valves. In the first part, different experimental
techniques are compared to the measurements made in the Air Valves Test Bench built by Bermad CS at its factory in Evron
(Israel). The second part deals with the study of a collection of commercial air valves from different manufacturers. Finally, the
Wylie and Streeter discharge coefficient Cd for air valve characterization [1] has been obtained. The results have been also
compared with a simplified proposed model representation of the air valve.
