Abstract
A method for operating a pressure operated device in a wellbore includes conducting pressurized gas to a power fluid inlet port of a valve at a first pressure. The first pressure is selected to cause a shuttle in the valve to be positioned to enable flow of the pressurized gas through the valve to a power fluid flow port in communication with a power fluid inlet of the pneumatic device. Pressure of the pressurized gas is increased to a second pressure greater than the first pressure, whereby the shuttle moves to close the power fluid inlet port to flow and to vent the power fluid flow port to ambient pressure in the wellbore.
