The EPA has estimated that approximately 70,367 tons per year of Volatile Organic Compounds (VOCs) and 9,357 tons per year of Hazardous Air Pollutants (HAPs) have been emitted from equipment [including valves] leaks.
As our world is increasingly focused on the identification and eradication of fugitive emissions, the valve industry has a duty to engineer new products in support of this movement. This paper will explore the importance of, and how to achieve, True Zero Leakage with Modulating Pilot Operated Pressure Relief Valves at high operating pressures made possible by advanced bolt-on modulator technology.
