Abstract: A butterfly valve housing assembly for a butterfly valve having a closing element mounted in the housing so as to be rotatable about a vertically extending stem, comprising a housing consisting of plastic or light alloy, a vertically extending stem, a through-flow opening, arranged in the housing, accommodating the closing element, and flanges arranged at the ends, wherein at least one reinforcing element is arranged in the housing, which reinforcing element is connected to the flanges by means of force-absorbing means in such a way that internal pressure forces acting on the stem are absorbed by the force-absorbing means via the reinforcing element.

Abstract: Butterfly valve housing for a butterfly valve having a closing element mounted rotatably in the housing, wherein receiving openings are arranged in the housing between the two flange connection discs and between the reinforcement structure, wherein the receiving openings are directed from the outer circumference in the direction of the vertical centre axis, into which the inserts can be inserted into the housing, wherein the inserts are arranged form-fittingly in the receiving openings.
