Abstract
Disclosed is a power conversion system for controlling the flow of a hydraulic power signal between a power source and a hydraulic actuator having first and second ports. The power conversion system includes a control valve that is configured to selectively expose each of the first and second ports to one of the power source and a low pressure reservoir. An enabling valve having a disabled position, a first enabled position, and a second enabled position receives an input from the control valve and provides an output to the hydraulic actuator.
