Abstract
An interval control valve actuator includes an electrohydraulic pressure generator and an actuation pressure line extending between the generator and a valve. A hydraulic junction disposed in the actuation pressure line is selectively hydraulically joins the actuation pressure line to a backup pressure line. An interval control valve including a housing, a valve disposed in the housing, an electrohydraulic actuator hydraulically connected to the valve by an actuation pressure line. A hydraulic junction disposed between the electrohydraulic actuator and the valve and a backup pressure line hydraulically connected to the hydraulic junction, the backup pressure line being selectively hydraulically connectable to the actuation pressure line.
