[origin: CA3087647A1] The invention relates to a slide valve for chemical and/or petrochemical installations, in particular in a round, oval, or flat slide valve design, having a locking device (11), which can be moved by a slider rod (12) into an open and closed position, and a drive, which has an electric motor (13) for adjusting the slider rod (12). The locking device (11) has two locking plates (14, 15), between which a wedge arrangement (16) for pressing the locking plates (14, 15) onto housing sealing seats (17) of the slide valve is arranged and is connected to the slider rod (12). The drive has a spindle drive (18) which is flush with the slider rod (12) and is connected thereto for transmission of a positioning force.
