Section-balanced electric safety valve

An electric safety valve comprising:

• an electric actuator positioned in an interior chamber of the electric safety valve;
• wherein the interior chamber further comprises a dielectric fluid and the interior chamber is pressure and temperature compensated with a flow passage extending axially through the electric safety valve;
• a compensating subassembly configured to perform the pressure and temperature compensating;
• a protective sleeve separating the interior chamber from the flow passage;
• at least one compression spring rod coupled to a closure member capable of restricting or preventing fluid flow through the flow passage;
• and
• a magnetic coupling of the closure member to the electric actuator.

A production system for a wellbore, the system comprising:

• an electric safety valve comprising:
• an electric actuator positioned in an interior chamber of the electric safety valve;
• wherein the interior chamber further comprises a dielectric fluid and the interior chamber is pressure and temperature compensated with a flow passage extending axially through the electric safety valve;
• a compensating subassembly configured to perform the pressure and temperature compensating;
• a protective sleeve separating the interior chamber from the flow passage;
• at least one compression spring rod coupled to a closure member capable of restricting or preventing fluid flow through the flow passage;
• and
• a magnetic coupling of the closure member to the electric actuator;
• production tubing;
• wherein the electric safety valve is coupled to the production tubing;
• and
• a control system coupled to the electric safety valve.
