Antisurge valves must be responsive
in order to protect critical and
costly compressors from damage
during transients. Fisher precision
actuation technology enables a full
stroke up to 50.8 cm (20 inches)
in less than one second and better
than 1% positioning accuracy.
Fisher ENVIRO-SEAL low emissions
packing is designed and tested
for Fisher control valves to keep
fugitive emissions below 100 parts
per million volume (ppmv) in your
throttling application for tens of
thousands of cycles.
Many of Emerson’s standard Fisher
products are used in extremely
high-cycle applications, and must
be tested to more than one million
cycles. Those same standard
products are used in your olefins
plant to enhance reliability.
Fisher control valves are designed
and tested for robustness in
vibration applications. They are
subjected to additional testing
for millions of cycles at their
resonant (worst case) frequency
to enhance performance in your
facility.
Fisher control valve assemblies
are subjected to on-line, dynamic
performance testing to evaluate
their ability to reduce your
process variability. These tests
replicate how control valves are
used in your plant.
Supported with a 4,738 m

chamber, Emerson can quantify
noise from valves, piping, and
vents. This capability provides
insight to ensure highly accurate
noise prediction and helps you
comply with regulatory (IEC)
requirements.
