Beschreibung
Zusammenfassung:	A valve housing has a first flapper moveable from an open position in the housing in which two-way flow is allowed to a closed position in which only one-way flow is permitted. A first collet sleeve is moveable from a first position to a second position in the valve housing. The first collet sleeve in the first position retains the flapper valve in the open position. The collet sleeve is moveable from a first position to a second position which allows the flapper to move to a closed position. Un boîtier de valve comporte un premier clapet mobile entre une position ouverte dans le boîtier dans laquelle un écoulement bidirectionnel est possible et une position fermée dans laquelle seul un écoulement unidirectionnel est possible. Un premier manchon de serrage est mobile entre une première position et une seconde position dans le boîtier de valve. Le premier manchon de serrage dans la première position retient la valve à clapet en position ouverte. Le manchon de serrage est mobile entre une première position et une seconde position qui permet au clapet de passer à une position fermée.
