DVC6200 Digital Valve Controller

Test Product

The FIELDVUE DVC6200 digital valve controller is a HART communicating instrument that converts a two-wire 4-20 mA control signal into a pneumatic output to an actuator. It can easily be retrofitted in place of existing analog positioners on most Fisher and non-Fisher pneumatic actuators.

Features include

  • Linkage-Less Non-Contact Position Feedback— The high performance, linkage-less feedback system eliminates physical contact between the valve stem and the DVC6200. There are no wearing parts so cycle life is maximized.
  • Built to Survive—The field proven DVC6200 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.
  • Accurate and Responsive— The two-stage positioner design provides quick response to large step changes and precise control for small setpoint changes.
  • Travel Control/Pressure Fallback— Valve position feedback is critical to the operation of a digital valve controller. The DVC6200 can detect position feedback problems and automatically revert to I/P transducer mode to keep the valve operational.
  • Improved Maintenance Decisions— Digital communication provides easy access to the condition of the valve. Sound process and asset management decisions can be made by analysis of valve information through Fisher ValveLink software.
