Abstract: A slide valve for blocking a line conveying media includes a housing having a passage opening and a slider plate moveable within the housing at right angles to the passage opening. The slider plate can be displaced from an open position into a closed position blocking the passage opening tightly by a drive mechanism. A lateral seal is disposed in a respective groove in the housing above the passage opening on both sides of the slider plate at right angles to its direction of displacement. The inside and outside of the housing and the slider plate are provided with at least one layer forming a temperature barrier, and the lateral seal includes 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.

Abstract: A slide valve for blocking a line conveying media includes a multi-part housing having a passage opening and in which a slider plate operable by a drive component is moved longitudinally. To both sides of the slider plate, laterally to its direction of movement, a respective longitudinal seal is disposed above the passage opening in a longitudinal groove in the housing. Each longitudinal seal has an elastic sealing profile and bars adjacent to the latter. Each elastic sealing profile is preferably provided on the front side with two sealing lips spaced apart from one another, touching the slider plate, and in the central region with groove-shaped chambers on both sides.

Abstract: A slide valve, in particular for blocking a line conveying media, is provided with a multi-part housing (2) having a passage opening (3). Disposed in this housing (2) are two slider plates (4, 5), parallel to one another, moveable at right angles to the passage opening (3), and which can be moved from an open position into a closed position tightly blocking the passage opening (3) by means of a common drive mechanism (10). Means are provided for connecting the two slider plates (4, 5) to one another and to the drive mechanism (10), and which in the closed position allow a pre-determined relative movement of the slider plates (4, 5) in relation to one another in their direction of movement. Thus, even with tolerance deviations with regard to the slider plates and/or their counter-surfaces, a long-lasting blocking function of both slider plates is guaranteed.

Abstract: A resilient seat seal for a valve. The seal has a closed liquid-filled void therewithin, and the liquid redistributes within the seal as a portion of the seal is compressed, thereby causing effective sealing by all portions of the seal. Examples are shown with the seal used in a knife gate valve, a ball valve, and a butterfly valve. Preferably the seal is made of elastomer or polymer material such as GFLT (“good for low temperature”) FKM. The liquid within the void of the seal is preferably an antifreeze liquid such as ethylene glycol.

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.

Abstract: A slide valve, in particular for blocking a line conveying media, comprises a multi-part housing (13, 14) having a passage opening (12) and in which a slider plate (15) operable by a drive component is moved longitudinally. To both sides of the slider plate (15), laterally to its direction of movement, a longitudinal seal (20) is respectively disposed above the passage opening in a longitudinal groove (17) in the housing (13, 14). This longitudinal seal (20) respectively has an elastic sealing profile (21) and bars (22) adjacent to the latter. The respective elastic sealing profile (21) is preferably provided on the front side with two sealing lips (23) spaced apart from one another, touching the slider plate (15), and in the central region with groove-shaped chambers (25) on both sides.
