ABSTRACT:
A pressure activated valve and associated methods of using same provide increased functionality and convenience in actuating a tool operatively positioned within a subterranean well. In a described embodiment, a switch valve is utilized to control actuation of a downhole power unit. The switch valve is configured to cause actuation of a switch within the downhole power unit in response to a differential fluid pressure. The differential fluid pressure is created by applying pressure to the interior of a tubing string to which the valve is attached.
