Available Diagnostic Levels
DVC6200S HC
The HC version covers the functions most plants need for everyday valve control.
It supports HART communication, automatic calibration, valve characterization, and basic alert functions. For standard control valve applications, HC remains one of the most widely used configurations.
DVC6200S AD
The AD version includes additional diagnostic tools that allow maintenance personnel to evaluate valve condition in greater detail.
Functions such as Valve Signature, Dynamic Error Band, and Step Response testing can help detect friction changes, sticking valves, actuator wear, and other mechanical issues.
Many plants choose AD when implementing predictive or condition-based maintenance programs.
DVC6200S PD
PD is the most advanced diagnostic option available within the DVC6200S family.
PD is typically chosen by plants that want more than basic valve positioning.
In addition to the standard control functions, it gives maintenance personnel access to a wider range of diagnostic information that can be used when troubleshooting valve performance or planning maintenance activities.
For critical valves, many users prefer PD because it provides more operating data to work with.
Typical Applications
- Oil & Gas Processing
- Refineries
- Petrochemical Plants
- LNG Facilities
- Chemical Plants
- Power Generation Facilities
- Water Treatment Systems
- Industrial Process Control Applications
Why Customers Contact Us
Many customers reach out because:
- Their existing DVC6200S has failed and needs replacement
- The original model number is unclear
- They need help identifying HC, AD, or PD versions
- A shutdown project requires urgent delivery
- They need spare units for inventory planning
- They want pricing for multiple configurations
Our team can help verify the configuration and provide available options based on the information you have.
Q: Why Many Plants Continue to Use the DVC6200S
A: The DVC6200S has been around long enough that most maintenance teams already know it well.
It is used on a wide range of Fisher valve assemblies, supports both rotary and linear applications, and is available with different diagnostic levels depending on plant requirements.
For facilities already operating FIELDVUE instruments, replacing or expanding with another DVC6200S is often the simplest option.
