A vacuum lifting arrangement (10) having a lifting tube (30) and a suction foot (20) for engaging with an object (200) to lifted, is disclosed, said vacuum lifting arrangement having a pneumatic valve (40) fluidly connected to ambient air (80), wherein, during operation of the vacuum lifting arrangement, when an object is not engaged with the suction foot, an air-flow from the suction foot into the lifting tube is prevented by the valve which is in a closed position, and, upon generation in the suction foot of a pressure lower than the surrounding pressure, e.g. due to engagement with an object to be lifted, the valve will be in an open position, allowing an-air flow from the suction foot into the lifting tube. A lifting tube comprising a pneumatic valve for use in the lifting arrangement also disclosed.
