A system and method for controlling production fluid flow from a chamber extending between a casing disposed in a downhole bore and tubing disposed in the casing. A plurality of valves are disposed in respective openings formed in the tubing, and a passage is formed in each valve for connecting the chamber and the tubing interior. The valves are selectively closed to prevent any fluid flow through the passage, and selectively opened to permit fluid flow from the chamber, through the passage, and into the interior of the tubing. Thus, the volume of fluid passing from the chamber, through the valve members, and to the interior of the tubing is controlled.
