Abstract

A seal arrangement for a fluid valve includes: a first seal for sealing abutment against a pivotably adjustable valve body of the fluid valve; a second seal for sealing abutment against a valve housing of the fluid valve; and a separate, elastically deformable intermediate piece arranged between a first wall of the first seal and a second wall of the second seal. The intermediate piece has at least one axial section whose cross section has, in relation to the seal opening, a first, radially outer lateral surface and an opposite, second, radially inner lateral surface, and the radially outer lateral surface is at least sectionally concave, and the radially inner lateral surface is at least sectionally convex.
