摘要： Disclosed is a flow blocking valve (1) comprising a valve housing part (2) forming a flow duct (3) between a flow inlet (4) arranged at an inlet end (5) of the duct (3) and a flow outlet (6) arranged at an outlet end (7) of the duct (3), wherein a seat (8) is arranged at the flow outlet (6). The flow blocking valve (1) also comprises a displaceable valve blocking device (9) arranged to move inside the flow duct (3), wherein said blocking device (9) is arranged to block the flow through said valve (1) when being forced against said seat (8). The flow blocking valve (1) further comprises obstruction means (10) being displaceable in a direction substantially transverse in relation to a longitudinal direction of the flow duct (3), wherein the obstruction means (10) is arranged to controllably obstruct the passage of the displaceable valve blocking device (9) without completely disabling flow through the flow duct. Disclosed is also a vacuum lifting device (13) for fixating goods (14) by means of vacuum and a method for operating a vacuum lifting device (13) comprising at least one suction device (15) connected to at least one vacuum source (16) through a flow blocking valve (1). Furthermore, a vacuum lifting arrangement (26) for lifting one or more items (14) simultaneously is disclosed. The vacuum lifting arrangement (26) comprises a top frame (19) including one or more suction devices (15) connected to at least one vacuum source (16). The vacuum lifting arrangement (26) also comprises one or more curtains (20) extending downwards from the top frame (19), and displacement means (31) for maintaining a part of the one or more curtains (20) against the sides of one or more of the one or more items during at least a part of a lifting process, wherein an inside surface (21) of the one or more curtains (20) comprises an irregular surface geometry.
