A valve with an electrodynamic actuator includes a magnet device that generates a magnetic field and a drive element that is movable relative to the magnet device. The drive element is pivotally mounted and comprises a current-carrying air coil that is arranged in the magnetic field and is fixedly coupled to a coil carrier made of a non-magnetic material. Sealing surfaces for sealing valve seats are arranged on two opposite sides of the drive element, such that the sealing surfaces face in opposite directions. A housing is comprised of a plurality of plastic housing parts and a metallic encasement. The metallic encasement surrounds an upper area of the housing in which the electrodynamic actuator is arranged and at least partially surrounds a lower area of the housing in which fluid channels are arranged.

A membrane valve comprising a first and a second valve housing part and a membrane clamped between the valve housing parts comprises a peripherally surrounding bead on the membrane and a thin, axially movable membrane portion adjacent thereto. The bead is supported by the two valve housing parts and is provided with an undercut at a radial inner side. Further, a membrane for installation in a membrane valve is provided.
