An example fluid flow control member for use with a valve includes a body having a first seating surface to control a flow of fluid through the valve. The body defines a second seating surface oppo-site the first seating surface to control a flow of fluid through the valve. Additionally, the body defines an aperture to receive a stem of the valve, and a bore surrounded by the first seating surface to receive at least one of a seal or a sliding member each of which have a first surface to be en-gaged by a second surface of a spring seat coupled to the stem to control a fluid flow through the valve.

L'invention concerne des éléments de commande de débit destinés à être utilisés avec des soupapes. Un élément de commande de débit de l'invention destiné à être utilisé avec une soupape comprend un corps présentant une première surface de portée pour commander un écoulement de fluide dans la soupape. Le corps définit une seconde surface de portée opposée à la première pour commander l'écoulement de fluide dans la soupape. De plus, le corps forme une ouverture pour recevoir la tige de soupape et un trou entouré par la première surface de portée pour recevoir au moins un joint d'étanchéité ou un élément de coulissement, chacun d'eux ayant une première surface avec laquelle vient en contact une seconde surface d'un siège de ressort couplé à la tige pour commander un écoulement de fluide dans la soupape.
