Abstract

The invention is intended to simplify the installation and removal of the back-up plate (3) of a valve element (2) and to guarantee secure fixing of the back-up plate (3). A circumferential groove is provided in guide ribs (14) of the valve body (1). The back-up plate (3) has at least one flexible tongue (33), the free end of which is fixed in a securing rib (141). To secure the back-up plate (3) against rotation, the elasticity of the tongue (33) is exploited either by bending its free end out of the plane of the back-up plate (3) or by parallel displacement of the annular groove (151) of the securing rib (141) with the supported free end of the tongue (33) relative to the circumferential groove (15) of the other guiding ribs (14) and, to further facilitate installation, the securing rib (141) can be broadened in the direction of the seat (139). <IMAGE>
