Abstract: A gas lift valve assembly includes a housing and a check valve. The housing defines an inlet port and an outlet port, and includes an inner casing having a radial outer surface and a radial inner surface at least partially defining a main flow passage. The check valve includes a sealing mechanism disposed around the radial outer surface of the inner casing, and a valve member including an outwardly extending sealing segment. The valve member is moveable between an open position and a closed position in which the sealing segment sealingly engages the sealing mechanism.
