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.

Reduced Total Cost of Ownership

  • Broader pressure range can eliminate one stage of pressure regulation
  • Potential use as overpressure protection, removing the need for a separate device
  • Stronger actuation enables smaller valve sizing (Series 158/9)
  • Combined solenoid and motorized technology reduces system footprint and overall system cost
