Highly adaptable 1900 & 1900 Dual Media (DM) Series Safety Relief Valves.
The patented innovation of the Dual Media trim design makes it the first and only spring-loaded safety relief valve in the industry that is “dual certified”, as defined by API Standard 520 Part 1 – Sizing and Selection, 10th Edition. Dual Certified is defined as pressure relief valves that are both vapor/gas flow certified and liquid flow certified where dual certification is achieved without making any modifications or adjustments to the relief device when switching fluids during the flow testing. The 1900 DM trim is engineered to perform on both liquid and/or gas media with exceptional blowdown performance and is dual certified to meet dual media (liquid and gas) capacity stamping per ASME B & PVC Code Case 2787. The 1900 DM trim is ideal for any liquid or gas application, two-phase liquid and gas, flashing or multiple relief case scenarios.
