Abstract
The invention relates to a butterfly valve, comprising a passageway, a valve seat enclosing the passageway, a rotatable valve shaft which has an axis of rotation spaced from a plane through the valve seat, a valve plate member fixed to the valve shaft and being located in the passageway, and seal enclosing the valve plate member. The valve plate member has an open position and a closed position. At least in a plane through the seal in the open position, the width of the passageway adjacent to the valve seat as viewed from the valve seat in the direction of the axis of rotation is larger than the width of the passageway at the valve seat. Due to this configuration leakage via the seal in the closed position is avoided, because of minimal deformation of the seal in the open position. The butterfly valve has good resistance against irradiation and high-temperature necessary for enabling disinfection of the butterfly valve and a container to which it can be fixed and which is suitable for storage of sterilized products.
