An apparatus includes a tube including an inner surface, an inner diameter, and a length. The apparatus also includes a coil spring. The coil spring includes an outer surface, an outer diameter, and a plurality of coil elements arranged along a length of the coil spring. The coil spring can be positioned within the tube and the outer diameter of the coil spring can be less than the inner diameter of the tube. The coil spring can form a waveguide. Related methods of manufacture and systems are also described herein.

A flow control valve assembly with a plunger continuously movable between closed, intermediate, and open positions. The plunger has an uphole side and a downhole side opposite the uphole side, and both uphole and downhole sides are exposed to the same hydrostatic pressure in the well, resulting in a flow control device that can be operated with minimal power consumption and still withstanding high pressure loads.
