ABSTRACT:
The invention relates to a slide valve for flow lines that carry fluid. The slide valve includes a stationary valve plate and two separately movable sealing plates, which like the valve plate have a plurality of flow openings formed by ribs. Oppositely disposed pressure plates, moving toward one another, each close off one-half the area of the flow openings. The division of the closing motion considerably shortens the closing time of the slide valve and also allows flow openings that can be approximately twice as large in area as the ribs.
