Abstract
Herein described is a hydroelectric control valve (HCV) for a fluid pipeline including an inlet and outlet (or input and output) section attached to the same pipeline wherein fluid flows into and out of the HCV comprising a bell reservoir section and a seat reservoir section which are both capped, where the bell reservoir section and the seat reservoir section are aligned with each other and are also perpendicular to fluid flowing through the pipeline. A channel which can be electrically activated and thus controlled is attached to a bell section, such that a bell reservoir section includes a bell relief channel in fluid communication with an outlet section and also a separate hydraulic poppet channel in communication with a locating needle head. In addition, turbine and deactivation channels are employed such that the deactivation channel connects the input section and the seat reservoir.
