The present invention is directed to a valve (10) for controlling the flow of fluid through a component which includes a flow conduit (12) extending therethrough. The valve comprises a first closure member (40) for controlling the flow of fluid through the conduit, a second closure member (42) for controlling the flow of fluid through the conduit, and a valve stem (30) which is connected to both the first and second closure members. The stem is responsive to an external force to move the first and second closure members from a closed position, in which the fluid is blocked from flowing through the conduit by both the first and second closure members, to an open position, in which the fluid is permitted to flow through the conduit past both the first and second closure members.

L'invention concerne une soupape destinée à réguler le flux de fluide s'écoulant dans un élément qui comprend un conduit d'écoulement s'étendant à travers lui. La soupape comprend un premier élément de fermeture pour réguler le flux de fluide traversant le conduit, un second élément de fermeture pour réguler le flux de fluide traversant le conduit et une tige de soupape reliée à la fois au premier et au second élément de fermeture. La tige réagit à une force extérieure de manière à faire passer le premier et le second élément de fermeture entre une position fermée où le fluide est empêché de s'écouler à travers le conduit par le premier et le second élément de fermeture, et une position ouverte dans laquelle le fluide peut s'écouler à travers le conduit, au-delà du premier et du second élément de fermeture.
