Abstract
A gas lift valve is provided with increased longevity, reliability for preventing backflow, and/or scale resistance. A wide cylindrical sliding member stabilizes axial movement of a valve element in the gas lift valve. A wide spring around the sliding member biases the valve element toward closure during back flow. The spring is physically supported and guided by the sliding member and protected from gas flow injection by the same sliding member. A poppet shape of the valve element provides a consistent closing seal, and the sliding member protects the valve seat and poppet from full force of an injected gas.
