1. A valve for regulating the flow of a medium,
with a housing defining a fluid flow cross-section area and
with at least three valve discs,
wherein at least one valve disc is arranged in the housing so as to be non-rotatable,
wherein at least two valve discs are arranged so as to be rotatable relative to the at least one valve disc arranged so as to be non-rotatable,
wherein the valve discs each have at least one passage opening,
wherein the passage openings are designed in such a way that in a first relative position of the valve discs the flow of the medium is blocked and in a second relative position it the flow of the medium is maximally open and
wherein the passage openings are designed in such a way that in the second relative position the passage openings of the valve discs expose an opening area of more than 50% of the flow cross-section area,
wherein
the valve discs have an identical geometry.
