FLUID DELIVERY PRESSURE CONTROL SYSTEM

摘要

System and method for controlling process fluid flow to maintain a set delivery pressure at varying demand, including a fluid-loaded, self-operated main regulator and a method for providing the loading pressure therefor. The system also includes a flow restrictor for metering the loading fluid flow, a back-pressure regulator for controlling the loading fluid pressure, and a temperature-actuated regulator for venting loading fluid when the process fluid temperature varies from a selected range.
