Remote-Mount Digital Valve Controller Handles Extreme Temperatures
Emerson’s Fisher Fieldvue DVC6205 remote-mount digital valve controller handles applications in which accessibility, extreme temperatures (up to 120°C / 250°F), 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 300 feet away in a less severe or more accessible environment.
The remote valve mounted feedback unit utilizes the Fieldvue linkage-less, 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.
