A milking device for milking a dairy animal, comprising:

• a teat cup with a cup wall and a teat liner and a pulsation space situated in between, and
• a pulsation device connected to the pulsation space, the pulsation device 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 comprising:
• a first supply line comprising a first operable valve for supplying a first pressure, the first supply line being controllable by the first operable valve,
• a second supply line comprising a second operable valve for supplying a second pressure, the second pressure being a lower pressure than the first pressure, and the second supply line being controllable by the second operable valve, and
• a control unit configured to generate control signals for operating the first valve and the second valve,
• wherein the first valve is a controllable valve having a passage which is adjustable by means of the control signals,
• wherein the passage of the first valve and a passage of the second valve are simultaneously adjustable by the control unit via the control signals during at least one pulsation phase.
