1. A system comprising:
tubing;
an interval control valve (ICV) coupled to the tubing, the ICV having an open side and a close side;
a first hydraulic line and a second hydraulic line that are coupled with a hydraulic power system;
a first electrical power line and a second electrical power line coupled with an electrical power source; and
a set of one or more housings that enclose,
a shuttle valve coupled with the first and the second hydraulic lines and hydraulically coupled with a first normally closed (NC) solenoid valve (SOV) and a second NC SOV;
the first NC SOV and the second NC SOV respectively coupled with the first and second electrical power lines;
a first check valve hydraulically coupled with the first hydraulic line, a second check valve, and both the first and second NC SOVs;
the second check valve hydraulically coupled with the first and second NC SOVs, the first check valve, and the second hydraulic line;
a flow regulator hydraulically coupled between the first NC SOV and the second NC SOV;
a first inverse shuttle valve hydraulically coupled with the first hydraulic line, a dynamic flow regulator, a second inverse shuttle valve, and the open side of the ICV;
the dynamic flow regulator having a first port that is hydraulically coupled to an NC hydraulic activated pilot cartridge and a second port that is hydraulically coupled with the first and second inverse shuttle valves;
the second inverse shuttle valve hydraulically coupled with the second hydraulic line, the second port of the dynamic flow regulator, the first inverse shuttle valve, and the close side of the ICV; and
the NC hydraulic activated pilot cartridge hydraulically coupled with the first and second NC SOVs, the shuttle valve, and the first port of the dynamic flow regulator.
