Abstract
A diaphragm assembly for a diaphragm valve is described, which has a diaphragm which includes a functional portion adapted to cooperate with further components of the diaphragm valve and to separate opposite chambers. The diaphragm further includes a tab projecting laterally from the functional portion and having a through-opening provided therein. A marking element is fastened in the through-opening. In addition, a diaphragm valve having such a diaphragm assembly is presented.
Claims15
A diaphragm assembly for a diaphragm valve, comprising:
- a diaphragm which includes a functional portion adapted to cooperate with further components of the diaphragm valve and to separate opposite chambers;
- and
- a tab projecting laterally from the functional portion, wherein a through-opening is provided in the tab, and a marking element is fastened in the through-opening;
- wherein the diaphragm is a multilayer diaphragm, and the through-opening extends through all layers of the multilayer diaphragm;
- wherein in an installed position, the diaphragm comprises an upper side and a lower side;
- and
- the marking element has substantially the same color as the lower side, the color being an indicator for the material on the lower side, or
- the marking element is made from the same material as the lower side, or
- the marking element has a shape being an indicator for the material on the lower side.
A diaphragm valve comprising a diaphragm assembly for a diaphragm valve, comprising a diaphragm which includes a functional portion adapted to cooperate with further components of the diaphragm valve and to separate opposite chambers, and a tab projecting laterally from the functional portion, wherein a through-opening is provided in the tab, and a marking element is fastened in the through-opening;
- wherein the diaphragm is a multilayer diaphragm, and the through-opening extends through all layers of the multilayer diaphragm;
- wherein in an installed position, the diaphragm comprises an upper side and a lower side;
- and
- the marking element has substantially the same color as the lower side, the color being an indicator for the material on the lower side, or
- the marking element is made from the same material as the lower side, or
- the marking element has a shape being an indicator for the material on the lower side.

- wherein the diaphragm is a multilayer diaphragm, wherein a first diaphragm layer is an elastomer layer and a second diaphragm layer is made of PTFE;
- wherein in an installed position, the diaphragm comprises an upper side and a lower side;
- and
- the marking element has substantially the same color as the lower side, the color being an indicator for the material on the lower side, or
- the marking element is made from the same material as the lower side, or
- the marking element has a shape being an indicator for the material on the lower side.
