Abstract

A butterfly valve with a valve disk mounted to swivel about an axis of rotation inside a housing and torsionally rigidly connected to a drive shaft pivotably mounted inside the housing. To ensure a connection which, from the standpoint of production engineering, is simple, yet secure, the valve disk is torsionally rigidly connected to the drive shaft by means of a minimum of two tapered pins engaging opposite sides of the drive shaft.
