Valve for negative pressure handling device or negative pressure clamping device, and negative pressure handling device

摘要

Valve with a valve housing which has a vacuum supply side and a suction side, with a flexible dividing wall which delimits a control space in the valve housing. A valve body which is arranged on the flexible dividing wall and can be moved between an open position and a closed position, wherein the valve body has a sealing portion which, in the closed position, bears against a sealing seat in order to seal the vacuum supply side with respect to the suction side. The volume of the control space is reduced with deformation of the flexible dividing wall and the valve body is moved from the open position into the closed position. The valve body has a suction side passage, and the sealing portion and the sealing seat are arranged in such a way that, in the closed position, the flow connection through the suction side passage is sealingly closed.
