The invention relates to a vacuum valve for the substantially gas-tight closure of an opening, comprising a closure element having a closure side and a coupling unit arranged on a rear side opposite the closure side, and a valve wall having valve seat surrounding the opening. The valve further comprises a linear drive unit enabling the closure element to be adjustable in at least two adjustment directions. The closure element is adjustable between an open position releasing the opening, an intermediate position pushed over the opening and a closed position closing the opening. The vacuum valve comprises a guide for the closure element associated with the opening. The closure element comprises a guide element interacting with the guide during an adjustment from the open position to the closed position and back.
