Internal valve apparatus are described. An example internal valve includes a body (102) having a valve seat (202) disposed between an inlet (206) and an outlet (208). A flow control member (110) operatively coupled to the body moves between a first position in which the flow con-trol member engages the valve seat to restrict the flow of fluid through the valve and a second position in which the flow control member is spaced from the valve seat to allow the flow of fluid through the valve. The exam-ple internal valve further includes a removable actuation member (114) disposed within the body and responsive to a fluid pressure to cause the flow control member to move between the first and second positions.

On décrit des appareils internes pour soupapes. Un appareil interne illustratif pour soupape comprend un corps (102) doté dun siège (202) de soupape disposé entre une entrée (206) et une sortie (208). Un organe (110) de régulation du débit couplé fonctionnellement au corps se déplace entre une première position où lorgane de régulation du débit interagit avec le siège de soupape de façon à limiter le débit de fluide à travers la soupape et une deuxième position où lorgane de régulation du débit est écarté du siège de soupape de façon à permettre lécoulement de fluide à travers la soupape. Lappareil interne illustratif pour soupape comprend en outre un organe (114) amovible dactionnement disposé à lintérieur du corps et réagissant à une pression de fluide pour amener lorgane de régulation du débit à se déplacer entre la première et la deuxième position.
