  • GATE VALVE
    Publication number: 20090114872
    Abstract: A gate valve comprising a first part (10), a second part (12), and inlet/outlet parts (14), wherein the first and second parts define a cavity in the body and where a wedge (18) is movable in said body. The gate valve comprises guiding objects (22; 22?) on generally opposite sides of the wedge for guiding said wedge movement, where a major part of each guiding object is accommodated in the first part, and a portion of the guiding object extends into a region of the cavity defined by the second part, thus essentially overlapping an area of said part. The guiding objects may be releasably mounted or be integral with the valve housing upper part.
