"UDT Make" Dummy Valves is a retrievable dummy valve used to blank off communication between tubing and casing. 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. During the life of the well, gas lift valves installed above the fluid level can be replaced with dummies to block off injection gas. They are available in 1 and 1- 1/2 inch sizes.
