The results of investigations of an interface valve flow capacity in a vacuum sewage system have been presented. The investigations were carried out in an experimental vacuum sewage system installation, built in a laboratory. The flow of liquid and air through the interface valve was measured for three opening times: 6, 9, 12 s. Based on the obtained results, nomograms were carried out to determine the coefficient f and the interface valve flow capacity. The nomograms may be used in design processes and in exploitation of the RoeVac type vacuum sewage system.
