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 conduit and a second hydraulic conduit 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 first one-way flow regulator coupled with the first hydraulic conduit and hydraulically coupled with a first normally closed (NC) solenoid valve (SOV) and a second NC SOV;
the first NC SOV coupled with the first electrical power line;
the second NC SOV coupled with the second electrical power line;
a second one-way flow regulator coupled with the second hydraulic conduit and hydraulically coupled with the first NC SOV and the second NC SOV;
a first dynamic flow regulator having a first port that is hydraulically coupled to the first NC SOV, and having a second port that is hydraulically coupled to the close side of the ICV; and
a second dynamic flow regulator having a first port that is hydraulically coupled to the second NC SOV and having a second port hydraulically coupled to the open side of the ICV.
