Schließhahn nach einem der Ansprüche 1 bis 11, dadurch gekennzeichnet, dass das Organ (5) zum Steuern zwischen einer ersten sogenannten "Schließposition", in der das Organ (5) zum Steuern das Organ (4) zum Regulieren in eine Konfiguration zum Schließen des ersten Entnahmekreises (3) stellt, und einer Vielzahl von zweiten sogenannten "Öffnungspositionen" beweglich ist, in denen das Organ (5) zum Steuern das Organ (4) zum Regulieren in jeweiligen Öffnungskonfigurationen des ersten Entnahmekreises (3) so anordnet, dass das Fluid zur Zirkulation mit einem festgelegten Durchsatz und/oder Druck von dem stromaufwärtigen Ende (13) zum stromabwärtigen Ende (23) zugelassen ist, und dadurch, dass, wenn sich das Organ (5) zum Steuern in seiner ersten Schließposition befindet, das Magnetfeld des magnetischen Elements (12) den zweiten Sensor (16) aktiviert, um die Unterbrechung der Stromversorgung des ersten Sensors (15) durch die Stromversorgungsquelle (7) auszulösen, und dadurch, dass, wenn sich das Organ (5) zum Steuern in mindestens einer der zweiten Öffnungspositionen befindet, das Magnetfeld des magnetischen Elements (12) den zweiten Sensor (16) nicht aktiviert und die Stromversorgung des ersten Sensors (15) durch die Stromversorgungsquelle (7) erlaubt.
  13. Schließhahn nach einem der Ansprüche 1 bis 11, dadurch gekennzeichnet, dass der erste Sensor (15) konfiguriert ist, um periodische Messungen mit einer kontrollierten variablen Frequenz durchzuführen, insbesondere eine erste erhöhte Frequenz innerhalb eines Zeitintervalls nach Erfassen eines Übergangs des Organs (5) zum Steuern von der ersten Position in eine zweite Position und eine zweite reduzierte Frequenz unterhalb der ersten Frequenz nach einem festgelegten Zeitintervall und/oder wenn der von einem Drucksensor in der Flasche gemessene Druck einen Druck unterhalb eines bestimmten Schwellenwerts erfasst, das heißt, dass die Messung des ersten Sensors je nach Zeit und/oder Situation unterschiedlich getaktet sein kann: eine schnelle Reaktionszeit beim Öffnen des Schließhahns, dann seltener, wenn der gemessene Druck z.B. eine leere Flasche anzeigt.
  14. Schließhahn nach einem der Ansprüche 1 bis 13, dadurch gekennzeichnet, dass das Organ (5) zum manuellen Steuern in eine Vielzahl von verschiedenen Positionen beweglich ist, die den jeweiligen unterschiedlichen Durchsatz- und/oder Druckeinstellungen entsprechen, die durch das Organ (4) zum Regulieren im Kreis auferlegt sind.
  15. Druckfluidflasche, dadurch gekennzeichnet, dass sie einen Schließhahn nach einem der Ansprüche 1 bis 14 umfasst.
