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.
New design of Emerson's DVC6000 digital valve controller eliminates the need for an additional seal or associated wiring termination box
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 recognised 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 standalone 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.
