Abstract:
An apparatus that is usable with a well includes a gas lift valve and an isolation member. The gas lift valve includes a valve element that is located between an annulus and a passageway of a tubing. The valve element is adapted to selectively open and close to control fluid communication through the valve element. The isolation member is adapted to in a first state, isolate the valve element from at least one of the annulus and the passageway and in a second state, permit fluid communication between the valve element and the annulus or passageway.
