High-Pressure Gas Regulator Products
From the Technology Leader
Precisely engineered to provide reliability and easy maintenance.
Our global customers and future customers require precise regulation of high-pressure transmission
pipelines that move natural gas. To meet their needs, Emerson Process Management Regulator
Technologies (Emerson Process Management) EZH and FL Series specifi cally handle high pressures
found in gas transmission lines. These regulators have been engineered to exacting standards to
control the fl ow of gas under very high pressure as it moves along the pipeline. Our high-pressure gas
regulators are carefully designed, thoroughly tested and developed to handle higher system pressures,
ensuring gas delivery and reduced noise output, resulting in increased capacity without emission of
natural gas.

Transmission skids
custom-made for any application.
Emerson™ has many years of experience
designing and assembling regulating
and metering stations. An array of
standard and customized installations is
available for transmission applications.
Our pressure-reducing stations can be
developed for open air, underground or

Source Treatment
Due to high pressure-drop ratios, aerodynamic noise is generated by the
turbulence created in the fl ow stream as gas travels through the port. Source
treatment with our Noise Attenuation Technology utilizes multiple orifi ces of
special size, shape and spacing, reducing noise-producing interactions.
