Abstract
Systems and methods for providing and energizing a seal gland assembly on a valve in a tubing hanger are described. A seal gland assembly comprising a first seal, a second seal, and a third seal is provided in a seal gap formed longitudinally between a spacer and a seal prep of tubing hanger threads and laterally between a bore wall of the tubing hanger and a sidewall of the valve. As the valve is threaded into the tubing hanger, the seal prep of the tubing hanger presses the first seal into the second seal, the second seal is then pressed into the third seal, pressing the third seal against the spacer compressing the first seal, the second seal, and the third seal approximately filling the seal gap.
