Abstract

The sliding stop valve has two sealing components mounted on a spindle, by means of which they are moved in and out of the passage to be shut off. The components are moved to and from each other so as to be pressed simultaneously against a seat or freed from it. The parts moving the components (22, 23) together and apart include flexible parts such as springs (21) or a medium under pressure, and which hold the components against the seats (4) with a controlled force not dependant, or only slightly dependent, on the reactive force exerted by the seats on the components. The components can be moved together and apart by turning the spindle (16), this having an eccentric (18) acting against the springs.
