Valve having a modular activation system

A resource exploration and recovery system comprising:

• a surface system;
• a subsurface system including a well bore extending into a formation, the well bore having a toe;
• a tubular string extending from the surface system into the well bore toward the toe, the tubular string supporting a valve comprising:
• a body including a wall having an outer surface, an inner surface defining a passage, an opening extending from the passage through the outer surface the outer surface including a recess;
• a valve sleeve arranged in the passage and selectively positioned over the opening;
• and
• a valve actuator module detachably mounted in the recess, the valve actuator module including a housing having an inlet fluidically exposed to the passage, an outlet fluidically exposed to the valve sleeve, and a valve member arranged between the inlet and the outlet, the valve member including an actuator delay mechanism.

A method of selectively shifting a valve sleeve comprising:

• detachably mounting a valve actuator module to a tubular;
• applying a fluid force through the tubular into an inlet of the valve actuator;
• shifting a valve member arranged in a valve chamber of the valve actuator allowing the fluid to pass from the inlet to an outlet of the valve module;
• applying the fluid pressure from the outlet to a sleeve in the tubular;
• and
• shifting the sleeve with the fluid pressure.
