Valve controller with stainless steel housing for corrosive environments!

Fisher® FIELDVUE™ DVC6200 stainless steel housing and sealed construction prevents corrosion damage to components

The Fisher® FIELDVUE™ DVC6200 digital valve controller family, from Emerson,  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 utilise a patented 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.

With over one million units installed worldwide, FIELDVUE digital valve controllers prove highly suited to difficult process environments, where they provide unmatched valve operation. The DVC6200 series is offered with CSA, IECEx, ATEX and FM hazardous area approvals as well as other certifications/approvals. It is also listed in the Lloyd’s Register for industrial, marine and offshore use.
