1. A slide valve or the like, comprising:

  • a slightly wedge-formed valve member arranged to close a flow duct in said valve by a cross-wise movement relative to said duct;

    said valve having annular sealing surfaces surrounding said flow duct and being engageable by sealing side portions of said valve member for closing said valve;

    said sealing side portions of the valve member being considerably narrower than said annular sealing surfaces surrounding said flow duct, and being in the closing position of said valve, located relative to said annular sealing surfaces at a relatively great distance from the inner edge of said annular sealing surfaces;

    said sealing side portions of the valve member being located each to a separate unit journalled in a body portion of said valve member; and

    flexible pins eccentrically located relative to said slide units for causing rotation thereof when said slide units come into contact with said flexible pins at an extreme open position to achieve even wear on the sealing side portions of said valve member.
