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.

Valve with electrodynamic actuator

A valve includes an electrodynamic actuator which has a magnet arrangement for generating a magnetic field and a control element movable relative to the magnet arrangement. The control element includes an energizable coil which is arranged in the magnetic field and is firmly coupled to a coil carrier. The control element is movable between at least two defined positions. There are provided permanent-magnetically interacting holding force which retain the control element in at least one of the defined positions, even when the coil is currentless.
