1. A system, comprising:
a valve connectable into a well string, the valve being shiftable between a plurality of modes to control flow of fluid in a downhole environment, the valve comprising an outer piston movable with respect to an inner piston sealing structure;
an actuation system connectable into the well string and operatively coupled with the valve, the actuation system being electronically controlled to cause the valve to shift to a desired mode of the plurality of modes; and
a sensor system comprising a plurality of sensors positioned along the well string to provide data indicative of a current mode of the plurality of modes of the valve, wherein the plurality of sensors comprise two or more pressure sensors configured to measure respective actuating fluid pressures on both sides of the outer piston and provide differential pressure feedback based on the measured respective actuating fluid pressures to the actuation system.
