A control valve and a membrane for a moving a valve disk of a control valve between a first position and a second position are provided. The membrane has a central axis perpendicular to an extension plane of the membrane. The membrane includes an outer annular rim portion, a central portion configured to be connected the valve disk, and a flexible portion that is annular and provided between the central portion and the outer annular rim portion. The membrane is flexible to permit the central portion to move back and forth along the central axis, thereby permitting the valve disk to move to one of the first position and the second position. The membrane is designed with an inherent pre-tensioning of the flexible portion, which permits the membrane to exert a force on the valve disk from the first position towards the second position.

An arrangement is provided in a milking system for simultaneous milking of a plurality of milking animals, wherein the milking system comprises a plurality of milking positions (P-P) and an arrangement for establishing identities of and expected milking times for the milking animals. Each of the milking positions is provided with teat cups, which are attached to the teats of a milking animal and are connected to a source of vacuum to milk the milking animal. The inventive arrangement comprises means () for determining a milking position, at which the milking animal having the longest expected milking time is present, based on the established identities and expected milking times; and a device () for performing an action with respect to the milking system in response to the determination.
