Emerson Process Management’s Fisher Fieldvue DVC6205 remote-mount digital valve controller proves an ideal solution for applications in which accessibility, extreme temperatures (up to 120°C), extreme vibration or confined space, make integral mounting difficult or impractical.
Industries such as pulp and paper and nuclear power, have typically preferred to isolate valve mounted instruments from harsh environments. With the DVC6205, only the valve position feedback is mounted on the control valve, while the remainder of the digital valve controller can be mounted over 90 metres away in a less severe or more accessible environment.
The remote valve mounted feedback unit utilises the patented Fieldvue non-contact feedback technology, in which physical contact has been eliminated between the valve stem and the instrument. With no linkage to wear, loosen, corrode or vibrate, the feedback unit can withstand a plant’s operating extremes.
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.
