A piloting actuator valve controls flow in a well. The piloting actuator valve is combined with a downhole completion and utilizes a pilot valve to control actuation of a main valve. A controllable actuator is coupled to the pilot valve and enables selective control over the pilot valve which, in turn, controls the state of the main valve.

Servocommande pilote qui règle le débit dans un puits. La servocommande pilote est combinée à une complétion de fond de trou et utilise une soupape pilote pour commander l'actionnement d'une soupape principale. Un actionneur commandable est couplé à la soupape pilote et permet un contrôle sélectif de la soupape pilote, à son tour, contrôle l'état de la soupape principale.
