Description
According to API Standard 520 Part 1-Sizing and Selection, 10th Edition, the Dual Media trim design’s proprietary innovation makes it the first spring-loaded safety relief valve in the industry to be “dual certified.” Pressure relief valves that are dual certified—that is, both vapor/gas flow certified and liquid flow certified—are known as dual certified. Dual certification is accomplished without requiring any changes or adaptations to the relief device while changing fluids during flow testing. According to ASME B & PVC Code Case 2787, the 1900 DM trim is dual certified to meet dual media (liquid and gas) capacity stamping and is designed to operate on both liquid and/or gas media with superior blowdown performance. The DM trim from 1900 is perfect for any liquid or gas application, two-phase liquid and gas, flashing or multiple relief case scenarios.
