Reliability
Rodless, non-contact position feedback - The high-performance, rodless position feedback system eliminates direct contact between the valve stem and the DVC6200 digital valve controller. This eliminates wear and tear on the components, which extends their cycle life.
Durable - The field-tested DVC6200 instrumentation comes with its own electronics that are fully sealed for a wide range of vibration, temperature, and corrosive environments. A junction box for severe weather isolates field wiring from the rest of the instrument.
Performance
Accurate Control and Fast Response-The two-stage positioner design facilitates fast response to large step changes and accurate control of small set point changes.
Travel Control/Pressure Drop - Valve position feedback is critical to the operation of digital valve controllers, and the DVC6200 Digital Valve Controller automatically switches to I/P converter mode when a valve position problem is detected to ensure proper valve operation.
Application Flexibility
Enhanced Assurance - The DVC6200 digital valve controller is a HART communication device, so information can be accessed from anywhere in the loop. This flexibility reduces the likelihood of equipment exposure to hazardous environments and makes it easy to assess whether a valve is difficult to reach its target location.
Faster Commissioning - HART communication allows the user to quickly commission circuits on local or remote valve assemblies using a variety of tools.
Easy Maintenance - The Fisher DVC6200 digital valve controller is modular in design. Critical operating components can be replaced without removing field wiring and pneumatic lines.
Economy of Use
Hardware cost savings-Significant hardware and installation cost savings can be realized by installing the hardware into an integrated control system. Valve accessories such as limit switches and position transmitters are not required because the information can be used through the HART communication protocol.
Extended uptime-The DVC6200 digital valve controller is self-diagnostic, allowing valve performance and health assessment even when there is no shutdown process or pulling of the valve assembly from the line.
Improve Maintenance Decisions-Digital communications make it easy to know the condition of your valves. By analyzing valve information with FisherValveLinkt software, sound process and asset management decisions can be made.
