19000 Series Threaded Safety Relief Valve
19000.1
19000 (SRV-1/Q2.02)
19000 Scope of Design
Introduction
The 19000 Series valves are designed and manufactured in compliance with ASME B & PVC, Section VIII and Section III (Class I, II and III) as well as being CE compliant to the EuropeanPressue Equipment Directive 97/23/EC. Seat tightness, blowdown and capacity on all types of media meets the industry needs for overpressure protection in chemical, petrochemical, refinery, power generation (nuclear and conventional) and other commercial applications.
General Information
The 19000 Series threaded safety relief valve has 316 stainless steel trim as standard material. Reliableperformance and easy maintenance procedures are characteristics of this valve (when properly installed in suitable applications for its design). The 19000 Series valves has three pressure classes, 19000L (5 through 290 psig), 19000M (291 through 2000 psig), and 19000H (2001 psig and up). Standard 19000 parts are used for both liquid applications and gas applications. It is designed for short blowdownon all medias, typically less than 10%. All 19000 Series valves have fixed blowdown. This means that the parts are designed so that there is no blowdown adjustment required when setting or testing the valve.
