Reclosable circulating valve for well completion systems

摘要

A valve for use in a tool positioned in a well that includes a body having a bore and a port connected to permit fluid communication between the well and the bore. A piston is supported in the body for movement between an open position to open the port and a closed position to close the port. A rupture disc is responsive to fluid pressure in the well and ruptures when a predetermined pressure is applied so that fluid pressure is communicated to the piston to move it from the closed position to the open position. A lock member secures the piston in the closed position after the piston moves from the open position to the closed position.
