Abstract
A valve is described, with at least one annular valve seat element (15; 22), with a spindle (26) and with a closing part (25) which is connected to the latter and the center point of which lies in the axis of the spindle (26). The closing part (25) can be brought onto the valve seat (14; 21) as a result of the axial displacement of the spindle (26). The closing part (25) and the valve seat element (15; 22) can, in the preassembled state, be adjusted relative to one another into a fitted closed position in the manner of a ball movement and/or of a radial and axial movement and, in the ready-assembled state, are fixed in this fitted closed position.
