1. A valve system comprising:
a first valve; and
a second valve,
wherein the first and second valves each comprise:
a housing with a plurality of housing openings to provide a fluid connection with an external flow channel for a fluid; and
a valve body that is arranged rotatably in the housing and has at least one connection channel for providing a fluid connection between at least two of the housing openings of the housing, wherein between the housing and the valve body, a seal having seal openings corresponding to the housing openings in the housing is arranged for sealing the fluid connections from an open environment,
wherein the valve body of the first valve and the valve body of the second valve are mechanically coupled with each other by a coupling device of the valve system, and
wherein the coupling device is designed such that the valve bodies are adapted to be rotated jointly by the coupling device when the valve system is in a first operating state and are each adapted to be rotated independently by the coupling device when the valve system is in a second operating state.
