Abstract

The invention relates to a valve diaphragm (10) for a diaphragm valve (100), the valve diaphragm (10) comprising a clamping section (12) following an imaginary perpendicular plane of an actuating axis (16), and a functional section (18) surrounding the clamping section (12) with a dry side (28) and a wet side (26); wherein the functional section (18) has a contact area (36) on the dry side (28) for contacting an actuating pressure piece (22), wherein the functional section (18) comprises a wave contour (30) with at least one wave crest (32) and / or with at least one wave trough (34) that at least partially, and in particular completely, surrounds the actuating axis (16), and wherein the at least one wave crest (32) and / or the at least one wave trough (34) passes through the contact area (36).
