A slide valve, in particular for blocking a line conveying media, is provided with a housing (2) having a passage opening (3) and with a slider plate (4) moveable within the housing (2) at right angles to the passage opening (3). The latter can be displaced from an open position into a closed position blocking the passage opening (3) tightly by means of a drive mechanism (10). A lateral seal (20) is respectively disposed in a respective groove (20′) in the housing (2) above the passage opening (3) on both sides of the slider plate (4) at right angles to its direction of displacement. The inside and outside of the housing (2) and the slider plate (4) are provided with at least one layer forming a temperature barrier, and the lateral seal comprises a high temperature-resistant layer or sealing compound. The risk of a leak into the atmosphere and/or in the passage during a fire or during extinguishing efforts is thus substantially reduced.
