The 2900 Series Gen II is a full-nozzle pilot-operated safety relief valve 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. This valves uses 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.
