Engineered to perform across a wide range of operating conditions, Emerson’s latest safety valve configurations support fuel train simplification, high-flow performance in low-pressure environments, and compatibility with alternative fuels, helping engineers future-proof boiler systems without added complexity.
Emerson also highlighted how its broader automation, measurement, and final control portfolio worked together to help boiler OEMs and operators improve efficiency, reliability, and environmental performance across the entire steam lifecycle — from combustion and fuel management to water quality and blowdown optimization to system monitoring and safety protection. By bringing multiple Emerson technologies together, customers were able to address key industry challenges such as rising energy costs, emissions compliance requirements, workforce skill gaps, and the need to minimize unplanned downtime.
