Description
The 2900/2900 TM Series Gen II is a full-nozzle pilot-operated safety relief valve (POSRV) matching API 526 direct-spring PRV dimensions. Its patented full-nozzle integral sense design allows for easy maintenance as well as simple spring-loaded to pilot-operated PRV conversions throughout the lifecycle of the valve. The 2900 Triple Media (TM) Series is the first full nozzle POSRV engineered to perform on liquid, air/gas, and steam media and is multi-media certified to meet multiple media capacity stamping per ASME B & PVC Code Case 2787. Both valve series use the same pilot valve technology as the 3900 Series including the ‘True Zero Leakage’ modulating pilot, providing a modernized overpressure protection solution for reducing carbon footprint and emissions.
