PCT No. PCT/EP87/00327 Sec. 371 Date Feb. 3, 1988 Sec. 102(e) Date Feb. 3, 1988 PCT Filed Jun. 25, 1987 PCT Pub. No. WO88/01211 PCT Pub. Date Feb. 25, 1988.The slide gate valve (20) has a damper unit (30) that can be adjusted by a drive unit and that can be moved to a position (A) lying outside of the closed position. In this position (A), the damper unit (30) is swingably held in a bearing (29) and guideways (21c) are lowered by a height (h) which releases the spring means (50) with respect to guideways (21a) along the remaining panel length. In this way, this damper unit can be swung out of the housing (24) in very simple fashion for the replacement of the eroded plates (22, 32), which is required very frequently and, after replacement of the plates, can be brought in the operating state again.
