  • Patent number: 11326425
    Abstract: A lift gas injection system that is used for introducing lift gas into a stream of production fluid includes a lift gas injection valve. A pressure protection system guards the injection valve against external overpressure by blocking communication to inside the injection valve housing when ambient pressure exceeds a set pressure. Communication is blocked by moving a valve member so that it obstructs flow through an opening in the housing. The system includes pressure actuated valve which has a platen mounted to an end of a bellows, and a valve member coupled to the platen. Surface area is reduced on the bellows side of the platen that creates a force imbalance on the platen from applied ambient pressure. At the set pressure the force imbalance moves the platen, and which pushes the valve member against the opening. A compressible pressure compensator inside the injection valve protects against internal overpressure.
