Abstract
A butterfly valve for controlling a gas pressure, in particular inside a cabin of an aircraft, comprises a valve housing () having a longitudinal axis (), a shaft () having a rotation axis (), and a closure member () connected to the shaft (). The closure member () is pivotally mounted in the valve housing () for rotation about the rotation axis () between an open position and a closed position. Moreover, the closure member () consists of a first disk () and a complementary second disk () which abut against each other. The first disk () and the second disk () are symmetrically arranged with regard to a symmetric axis () extending at a predetermined angle of inclination to the rotation axis (). Such a butterfly valve ensures a restricted cross-sectional area of the valve housing (), even if breaking of the closure member () occurs.
