Dummy And Equalizing Valves
D Series Valves are installed in side pocket mandrels by wireline to block the mandrel’s injection gas ports. Dummies can be run prior to or after completion for testing tubing, packers and other equipment. In new installations, dummies can be retained in the mandrels until gas lift valves are required to maintain production. Then, dummies are pulled and gas lift valves installed by wireline. Also during the life of the well, gas lift valves installed above the fluid level can be replaced with dummies to block off injection gas. These are available in 1 and 1 ½ inch sizes.
