Abstract: Pilot Operated Flexible Element Regulators are capable of providing very accurate control in natural gas transmission and distribution pipelines. The Pilot Operated Regulator provides advantages over both self-operated regulators and control valves. Primary benets include simplicity of operation and elimination of any fugitive emissions caused by atmospheric bleed gas. However, it is important to recognize the limitations of the pilot operated exible element regulator and apply it accordingly. The original Flexible Element Regulator, the Flex- o, was developed by the Grove Valve and Regulator Company circa World War II. The original intent for the regulator was to regulate water in submarine ballasting systems. However, Grove quickly recognized that the Flexo regulator product was ideally suited for pressure control applications in natural gas pipelines. Many advances have been made since the original Flexible Element was created more then fty years ago, but the same basic operational advantages and principles of operation remain unchanged.
