Abstract
An electric gas lift valve may comprise a casing, gas lift mandrel, one or more annulus, a tubing, a venturi sleeve, a needle, a governor, anti-rotational key, a rotational (rotating) bellow, a gearbox housing that houses a gearbox, an electrical motor, and an encoder. The bellow therefore allows the electrical motor, encoder and gearbox to be hermetically sealed against the external environment. Bellows that absorb torsion are provided. A bellow configured to absorb torsion comprising: a plurality of convolutions bent following a circular trajectory such that a start edge of a first convolution of the plurality of convolutions coincides with a finish edge of a last convolution of the plurality of convolutions, the start edge of the first convolution coupled to the finish edge of the last convolution.
