DIC Storm Valve, which is run above the DLT compression set packer. It provides a means to isolate the tubing below the packer and disconnect the running string by 22 turns of left-hand rotation.

The running string can be re-connected, and the valve opened to equalize the pressure for packer retrieval. The Storm Valve features an expendable plug that provides through-bore access for circulation or wireline passage.
