摘要： A valve for downhole chemical injection control, having a single chemical injection fluid line (2) to feed all the injection points, regardless of the number of zones, exclusively electrically-driven by a single electric cable (3), with embedded sensing electronics (7), which communicate and activate an electric motor (4), coupled to a multiposition sphere (5) for dosing the chemical injection fluid, which, according to the engine rotation, is moved, altering its position, to enable the passage of interest to be selected, according to the volume of chemical fluid to be injected, a single turn of the sphere being required to commute all the possible positions, the performance of which is low in power consumption, and for a short period of time, having after its positioning in the desired passage zero consumption to maintain this position.
