Abstract
A gate valve having two wedge-shaped disks that are suspended on a shaft and have sealing surfaces. The disks form an angle of 2.degree.-10.degree. to the shaft. The mutually facing sides of the disks are supported on a non-resilient ring with conical or spherical faces that rest against corresponding mating surfaces. The ring is positioned at the level of the sealing surfaces. The conical faces, or the secants of the spherical segment that form the conical faces, are at an angle of 15.degree.-50.degree. to the longitudinal axis of the shaft.
