Patent ID: 8006768

Claim:
A system for use in a well, comprising: a flow control valve having an actuator positioned to control flow; a fluid metering control module coupled to the actuator; a first hydraulic control line coupled to the fluid metering control module; and a second hydraulic control line coupled to the fluid metering control module, wherein the fluid metering control module comprises a metering piston disposed in a piston chamber and a piloted valve that respond to hydraulic inputs through at least one of the first and the second hydraulic control lines to close the piloted valve and thus enable shifting of the actuator by increments, each increment being limited by displacement of the metering piston against a stop, and wherein the first hydraulic control line and the piston chamber are connected via a crossover line extending through the piloted valve, wherein an appropriate pressure signal applied to the first or second hydraulic control lines causes the piloted valve to block flow along the crossover line.
