A milking device for milking a dairy animal includes a teat cup with a cup wall and a teat liner and a pulsation space situated in between, the pulsation space being connected to a pulsation device that is configured to apply a pressure that varies in pulsations to the pulsation space in order to open and close the teat liner. The pulsation device includes a supply line controllable by a first operable valve for supplying a first pressure, a supply line controllable by a second operable valve for supplying a second pressure lower than the first pressure, and a control unit configured to generate control signals for operating the first and second valves. At least the first valve is a controllable valve having a passage that is adjustable during at least one pulsation phase by the control unit.
