Claim Text:
1. A method for actuating a valve for a free-flowing medium, the medium having a changeable viscosity, the valve having an electromagnetically actuable closure member having a closure piece ( 20 ) which, in the closed position, bears against a valve seat ( 22 ), wherein an opening period of the opening position of the valve is controllable depending on the changeable viscosity of the medium in such a manner that, owing to different opening periods, substantially identically sized portions of the medium are dispensed during the opening period irrespective of the viscosity of the medium, wherein the opening period of the valve is controlled according to a stoppage period of the valve and resultantly induced cooling of the valve and of the medium in such a manner that, in the event of a prolonged stoppage phase during a limited operating period after the valve is restarted, a longer opening period of the valve is set, with the opening period being increasingly reduced as operation continues until a standard opening period is reached.
