Abstract

A shut-off valve mechanism for a shut-off and control valve has a generally cylindrical housing with inner and outer annular shoulder against which a valve seat disk is placed to prevent distortion of the valve seat disk. The valve control disk is pressed by spring forces against the valve seat disk from its upstream side and is entrained in rotation by a spindle passing through the inner annular shoulder and the valve seat disk.
