Abstract
A fluid control system is provided for controlling flow of a process fluid through a pipeline. The fluid control system can include a valve, one or more instruments in fluidic communication with the valve, and a pressurized chamber. In one example, the pressurized chamber contains the one or more instruments. In one example, the pressurized chamber has a dynamically variable pressure, which corresponds to a pressure in a downstream portion of the pipeline, such as a natural gas pipeline. In another example, the pressurized chamber captures instrument gas bled/leaked from the instruments and reinjects the instrument gas into the downstream portion of the pipeline.
