Gas Lift Valves

Gas lift valves are used in a gas-lift system to control the flow of lift gas from annulus around the production tubing to the production tubing. The gas lift valves are located in the gas lift mandrel. Gas lift mandrel provides communication with the lift gas supply in the tubing annulus. Operation of the gas lift valve is determined by preset opening and closing pressures in the tubing or annulus, depending on the specific application.
