Burgess-Manning inline diffusers and spargers are used in industrial piping systems where pressure reduction, steam expansion, and noise-related flow conditions must be addressed within the process line.
Unlike atmospheric vent silencers, inline diffusers are installed inside the piping network, typically downstream of a control valve or pressure reducing valve.
Inline diffuser assemblies are used to help manage the noise commonly associated with pressure reducing valve applications while supporting the pressure drop requirements of the system.

Spargers and dump tubes are used in steam expansion applications, including turbine bypass service upstream of steam condensers in combined cycle gas turbine and biomass power plant environments.
These components are commonly reviewed as part of a system-specific design because operating conditions can vary by flow path, valve arrangement, media, pressure drop requirement, and installation orientation.
Process Controls Corporation can assist with Burgess-Manning inline diffusers and spargers for applications requiring engineered noise control and process flow support inside industrial piping systems.
