Gas lift valve
Abstract:
A gas lift valve for use in a hydrocarbon well includes an elongated valve housing including an inlet port for receiving a fluid from an annulus of a hydrocarbon well, and an outlet port for delivering the fluid to a production tubing of the hydrocarbon well, and an elongated, internal valve body, which is movable along a longitudinal, central axis of the valve housing between a first end position and a second end position. In the first end position, a sealing surface of the valve body is in sealing contact with a valve seat surface of the valve housing prohibiting the fluid to flow from the inlet port to the outlet port, and in the second end position the sealing surface is separated from the valve seat surface allowing the fluid to flow from the inlet port to the outlet port. The outlet port is positioned at a terminal end of the valve housing.
