A system of sliding valves (16) wherein the inserts of multiple sliding valves may be shifted to an open position using a single shifting ball (66). Each individual sliding valve (16) has a movable insert (62) that, depending upon the position of the insert within the sliding valve, may either block, permit fluid to radially flow between the interior and exterior of the sliding valve at a first rate, or permit fluid to radially flow between the interior and exterior of the sliding valve at some different second rate. |
