Abstract
A bi-directional pressurized system with devices for and configured to mitigate issues associated with leak and creep phenomena at various stages throughout the system, including valves and controls to distribute a leaked amount of fluid prior to delivery to a pressure-sensitive destination and a pressure relief valve to bring an initial pressure within an acceptable range for distribution to reach a target pressure. A startup method for mitigating leakage of the system during a rest phase, including selectively reducing the initial pressure upstream of a pressure-sensitive destination.
