Abstract

A drive that is drivable by a pressure medium is described. The drive is used for a valve that can be used in hygienic applications. The drive includes a drive housing, in which a main piston is movable along a stroke direction by the action of the pressure medium and can be coupled to a rod, and a stop for limiting a movement of the main piston. To improve the drive, it is proposed that an additional piston is provided, which is movable by the action of the pressure medium. The stop can be carried along by the additional piston. The disclosure also describes a double-seat valve comprising such a drive and to a method for operating such a drive.
