Marshalltown, IOWA (March 20, 2008) – Emerson Process
Management has announced approval of the Fisher®
FIELDVUE®
DVC6000 digital valve controller for natural gas
applications, making the instrument an "energy-responsible"
choice for the natural gas industry. The CSA (Canadian
Standards Association) approved instrument is designed to
help customers improve plant safety. This new design for
natural gas applications eliminates the need for an
additional seal or an associated wiring termination box,
creating an integrated and more cost effective option to
actuating the valve assembly.
Natural gas from a process line is often used as a medium
to actuate the valve assembly. There has been a growing
industry concern regarding natural gas migrating down the
associated wiring conduit and exposing people who open
junction boxes and other connection points. Attempts by
various manufacturers and customers to use conduit glands
and seals have provided a stopgap solution. To prevent
natural gas from passing into areas not suitable for natural
gas, the DVC6000 instrument now provides an integrated
solution within the instrument that meets the CSA Single
Seal requirements per ANSI/ISA 12.27.01 for applications
such as this. Having met the single seal requirements, no
secondary seal will be required in Canada.
"Innovation around customer needs is priority one for
Emerson. The integration of a CSA gas certified conduit seal
into the FIELDVUE DVC6000 instrument has significant value
to the end user who pneumatically powers their field
instrument with process gas," commented Danny Nelson,
Emerson's vice president of instruments for Fisher products.
"Instrument qualification to CSA test requirements is
stringent. Our engineers recognized this and developed a
first to market solution, which provides installation cost
and time savings while meeting the necessary requirements
for plant safety."
To further Emerson's "energy-responsible" product, a low
bleed relay option is available for the DVC6000 instrument.
The low bleed relay reduces bleed rates by up to 1/6 and
still operates with superior performance to meet a plant's
process control needs. The low bleed option decreases the
environmental impact as well as cost of using natural gas as
the supply medium.
To become CSA approved, the DVC6000 unit had to withstand
rigid pressure testing and additional temperature cycle
testing from -57° C to 95° C to ensure that no gas would be
transmitted through the wiring termination area. The
FIELDVUE DVC6000 instrument is currently the only digital
valve positioner to be single seal approved by CSA for
natural gas service as a stand-alone device.
The FIELDVUE digital valve controller is a key component
of Emerson's PlantWeb
digital plant architecture, which networks intelligent
instruments that deliver diagnostic data for predictive
maintenance and increased availability of production and
distribution facilities. For additional information,
