Fisher DVC6200 PD valve positioner
Product Overview
The product we are seeing this time is the Fisher DVC6200 PD version, with only two pressure gauges in the picture, indicating that it is single acting. DVC6200 is a classic FILDVUE series intelligent digital valve locator with pressure gauge integration under Emerson Fisher, specially developed for industrial pneumatic control valves. It adopts the HART digital communication protocol and the PD model has an integrated pressure gauge module, which can read the output pressure of the gas source in real time and intuitively. It is widely used in process industries such as petroleum, natural gas, refining, chemical, power, and water treatment.
Main functional parameters of DVC6200
| Core Functions and Parameters of Intelligent Valve Positioner | ||
| Function Module | Function/Parameter Item | Detailed Description |
| Ultra-high Precision Regulation Performance | Control Precision Index | Control dead zone as low as 0.05%, stroke repeatability ±0.1%, can accurately match small flow, high pressure difference and micro-regulation working conditions |
| Actuator Adaptation | DVC6200 Supports universal switching of single-acting / double-acting pneumatic actuators, automatically recognizes valve direct/reverse action, with extremely simple commissioning steps | |
| Conversion Module Performance | Two-stage piezoelectric I/P conversion module, fast response speed, stable dynamic regulation, avoids valve oscillation and overshoot, and optimizes loop control quality | |
| HART 4-20mA Digital Communication, Intelligent Digital Management | Communication Protocol and Signal Transmission | Compatible with standard HART 5/HART 7 protocols, 4-20mA analog signal synchronously transmits valve opening, and digital channel uploads equipment diagnosis data |
| Remote Configuration and Calibration | Supports remote configuration, calibration, zero and span fine adjustment via handheld communicator (TREX/475), no need for on-site cover opening operation | |
| Equipment Management and Predictive Maintenance | Can be connected to DCS/AMS equipment management system, remotely access valve stroke curve, friction loss, air source leakage, diaphragm aging and other data to realize predictive maintenance | |
DVC6200 adaptability to harsh working conditions and environments
Complete explosion-proof safety certification
The DVC6200 machine has Ex ia, Ex d explosion-proof, and intrinsic safety explosion-proof certifications, meeting the requirements for use in Class I hazardous areas of petrochemical and oil and gas stations; Protection level IP66, dustproof, waterproof, corrosion-resistant, suitable for stable operation in outdoor installations and humid chemical workshops.
Stable operation over a wide temperature range
The DVC6200 standard operating temperature covers -40 ℃~+85 ℃, and there is no performance degradation in low-temperature cold mining areas and high-temperature refining equipment; The shell is made of corrosion-resistant die cast aluminum alloy, and the surface anti-corrosion coating is resistant to chemical water vapor and oil and gas corrosion. If you have a more stringent usage environment, the DVC6200 also supports a stainless steel corrosion-resistant casing.
Anti vibration and anti-interference design
Internal circuit with magnetic shielding to resist electromagnetic interference from frequency converters and high-power motors; Mechanical structure reinforcement, suitable for severe vibration conditions in compressor areas and pipelines, with no zero drift during long-term operation.
DVC6200 Diagnostic Level
You can see that the version in our picture is the PD version, which corresponds to the version of the fifth item in the table. Each Fisher locator has its own version, and it is important to confirm which version of valve locator you need when purchasing. Otherwise, your product may not be usable and result in loss.
