Claim Text:
1. A valve, comprising: a valve seat having a seat face and an orifice face, the orifice face defining a valve orifice extending through the valve seat, the seat face intersecting the orifice face at the valve orifice; and a valve closing body arranged on the valve seat and configured to selectively open and close the valve orifice, wherein the valve closing body has (i) an outer lateral surface that faces the seat face and that narrows conically towards the valve orifice and (ii) an elastic sealing bead formed integrally with the outer lateral surface and configured to directly contact the seat face so as to form a sealing fit with the seat face when the valve orifice is in a closed state, wherein the elastic sealing bead runs continuously around the outer lateral surface and forms a closed ring that bears against the seat face, wherein the valve closing body includes a guide mechanism configured to extend into the valve orifice to guide the valve closing body relative to the valve seat, wherein the valve closing body has one of a plate-like configuration and a dome-shaped configuration, wherein the guide mechanism has at least one fluid-conducting recess and at least one region configured to rest against the orifice face to guide the valve closing body, and wherein the at least one fluid-conducting recess and the at least one region are arranged on the guide mechanism such that the at least one fluid-conducting recess and the at least one region overlap along at least one plane disposed perpendicular to a direction of movement of the valve closing body within the valve orifice.
