A diaphragm valve, in particular for fluid media, includes a valve body, a diaphragm, and a connecting piece which can be actuated by a drive unit to act on the diaphragm, wherein the valve body and the diaphragm are made of plastic. Two mutually independent seals are provided for sealing the fluid medium with respect to the outside, wherein the valve body and the diaphragm are welded to each other, and the diaphragm is mechanically sealed between the drive unit, or an intermediate piece, and the valve body.

Diaphragm valve

Diaphragm valve having a valve body with an inlet and an outlet, a sealing membrane, and a connecting piece connecting the sealing membrane to a pressure piece of a drive. The valve body, the sealing membrane and the connecting piece are rigidly connected together to form an interchangeable, sealed valve body unit that can be connected to the drive. The connecting piece is molded on the sealing membrane, and the valve body and the sealing membrane are welded ultrasonically to one another.
