Abstract
A control valve is provided which may be incorporated within a fluid operating system. The valve has an internally-mounted check element which allows the valve to provide a fail-safe mode for a downstream device in fluid communication with the control valve. The invention includes the control valve, the valve in combination with a downstream device, and a method whereby the flow of pressurized fluid is controlled by operation of the control valve.
