ABSTRACT:
The gate valve comprises a body having a horizontal flow passageway, a vertical housing opening into the flow passageway and a closure member movable in the housing and passageway. The closure member has on each side a vertical U-shaped guiding bearing surface which projects from a sealing bead on the closure member and extends from the lower end of the closure member to a region located above the equatorial plane of the valve. This bearing surface permanently cooperates with a vertical bearing surface provided in the body between the flow passageway and a seat surface and having, when viewed along the flow axis a downwardly open C-shape.
