Zusammenfassung:	Described is a fluid control valve suitable to permit only gravitationally induced flow. The valve includes an inlet section in the form of a self-supporting trough-shaped section and an outlet section. The outlet section is formed from a flexible resilient material connected to the inlet section. The outlet section includes a sealing area with side gussets that hold a set of sealing surfaces of the sealing area apart from each other, where the sealing area is connected with the inlet section at its upper edge. L'invention concerne une soupape de commande de fluide appropriée pour permettre uniquement un écoulement induit par gravité. La soupape comprend une section d'entrée se présentant sous la forme d'une section en forme d'auge autoportante, et une section de sortie. La section de sortie est formée à partir d'un matériau élastique flexible relié à la section d'entrée. La section de sortie comprend une zone d'étanchéité ayant des soufflets latéraux qui maintiennent un ensemble de surfaces d'étanchéité de la zone d'étanchéité à distance les unes des autres, la zone d'étanchéité étant reliée à la section d'entrée au niveau de son bord supérieur.
