ABSTRACT:
A slide gate valve having a flangeless housing clamped between the ends of two pipelines which housing has an inner chamber, enlarged between the ends of the pipelines, for accommodating a stationary valve plate. An associated displaceable valve plate is provided with an annular insert having approximately the same inside diameter as the adjacent pipeline on the discharge side in the housing, against which insert the stationary valve plate is supported as a seal in a small annular area opposite the sealing surface between the insert and the pipeline. The remaining area of the stationary valve plate is free of support from both the insert and the housing.
