Digital Valve Controller’s Stainless Steel Housing Prevents Corrosion

Emerson’s Fisher Fieldvue DVC6200 digital valve controller family gains added capability with its all stainless steel housing that withstands the corrosive atmospheres often experienced in chemical plants, pulp and paper mills, as well as near-shore and offshore oil and gas installations.

All DVC6200 series instruments utilize a linkage-less, non-contact feedback design to detect valve position. This valve positioning technology eliminates any travel feedback issues caused by corrosion, high cycle or high vibration applications.

In addition to external protection, corrosion resistance is found within the stainless steel housing with the digital controller’s fully encapsulated printed wiring boards.  Internal component protection is further enhanced by a separate, weather-tight field wiring terminal box that isolates the field wiring connection from other areas of the instrument.
