ACTS Liner Closing Valve is a hydraulically actuated isolation valve designed to close the lowermost (toe) end of the liner once circulation operations are completed after liner installation. When the valve closes, the remaining hydraulic actuated equipment along the liner can then be functioned. The valve is closed by circulating an activation ball to the valve’s ball seat. Once the ball lands on the seat, pressure is applied from surface until a predetermined valve actuation pressure is achieved. An internal piston then shifts down and locks the valve closed which permanently closes the liner for additional pressuring operations. Large internal flow geometries have been incorporated into the valve to accommodate faster circulation rates and to prevent plugging. The valve is available in multiple thread and metallurgy configurations to be equivalent to required liner specifications for varying downhole operating environments.
