    摘要: The present invention relates to a pressure actuated valve for use in well completion assemblies. The valve is operable by pressure between three configurations. In a first configuration, the valve is in a locked-closed configuration. In a second configuration, the valve remains closed but is unlocked. In a third configuration, the valve is open. Also disclosed is a method of installing and operating a three pressure actuated valve in a well completion operation.
