摘要：
A drive device (10) for a valve (1), to a valve (1) for controlling a gas and/or liquid flow (40), and a system (60) for controlling a medium (40). The drive device (10) has a housing (11) for accommodating a coil (17d), which is fixed with respect to the housing (11), and a drive rod (14), on which a pole shoe (15d) and a permanently-magnetic element (16c) that is magnetized, or a soft-magnetic element (16c) that can be magnetized, in the axial direction of the drive rod (14) are attached such that the drive rod (14) can be moved with a translational motion relative to the coil (17d) by magnetic force. The drive rod (14) can be coupled to a shut-off body (33) of the valve (1) that can be moved with a translational motion such that a translational motion of the drive rod (14) affects a translational motion of the shut-off body (33) for opening and closing the valve (1).
