Emerson Automation Solutions
The FIELDVUE DVC6200 SIS digital valve controller is a HART communicating instrument for use in valve applications such as Emergency Shutdown, Emergency Blow Down, Emergency Venting, and Emergency Isolation.
HART Field Device
Linkage‐less Position Feedback—The high performance, linkage‐less feedback system eliminates physical contact between the valve stem and the DVC6200 SIS. This minimizes the affects of pipeline vibration and environmental corrosion.
Built to Survive—The field proven DVC6200 SIS instrument has fully encapsulated electronics that resist the effects of vibration, temperature, and corrosive atmospheres. A weather‐tight wiring terminal box isolates field wiring connections from other areas of the instrument.
Partial Stroke Testing (PST)—An on-line diagnostic to detect valve failure modes such as stuck valve by performing a user-defined ramp test, without disrupting the process. Testing can be automated or initiated manually.
Full Stroke Testing (FST)—An off-line diagnostic test to reveal additional valve failures undetected by the PST by performing a ramp over the entire valve travel range. FST is typically performed during a shut down. X0079
Ease of Use
Remote Access—Valve diagnostic information can be accessed anywhere along the loop, reducing personnel exposure to hazardous environments or difficult to reach locations.
Faster Commissioning—HART communication allows you to quickly commission loops with a variety of tools, either locally at the valve assembly or remotely.
Easy Maintenance—The DVC6200 SIS digital valve controller is modular in design. Critical working components can be replaced without removing field wiring or pneumatic tubing.
Hassle-free diagnostics—Partial stroke and full stroke tests result in an easy to understand Pass/Abnormal criteria including reason for any abnormal result.
