Abstract
A gas lift valve that has a longitudinally extending tubular body having an inlet and an outlet, a flow path extending between the inlet and the outlet, and a flow tube located inside the body. The flow tube is translatable in the axial direction between at least a first and a second position. A venturi orifice located inside the body along the flow path. A seal part is located proximate to the outlet of the body. A flapper is connected with the body by way of a hinge part and the flapper has at least a first open position and a second closed position. The closed position is where the flapper contacts the seal thereby closing the flowpath and the second closed position is where the flapper does not contact the seal and does not close the flowpath.
