Dummy & Equalizing Valves

"UDT Make" Dummy 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. 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.

Equalizing Valves

"UDT Make" Equalizing Valves with integral latches are designed to equalize tubing and casing or circulate prior to pulling the valve. They are also available in both 1 and 1-1/2 inch sizes.
