FISHER Fisher valve positioner: is FISHER's new generation of high-performance valve controller to respond to market demand and replace the DVC6000 series. Position feedback measurement and DVC6000 series flameproof/intrinsically safe housing and pneumatic architecture, adopt electronic components that continue existing on-board microprocessors, application software and function modules, and can adapt to all installation connection modes, support mainstream fieldbus communication and Predictive maintenance using embedded AMS ValveLink for easy system integration, high availability and high reliability.
FISHER Fisher Valve Positioner: Working Principle DVC6200 series supports HART, Ff, Profibus-PA mainstream fieldbus communication. Model DVC6200 supplies power for 4-20mADC+HART two-wire loop and provides control signals (equivalent impedance 550 ohms, maximum terminal voltage 11VDC); Model DVC6200f is used for FF FOUNDATION fieldbus and Model DVC6200p is used for Profibus-PA field Bus, both 9-32VDC bus powered and controlled digital signals. Models DVC6205, DVC6205f and DVC6205p are of split type construction and are equipped with independently mounted Model DVC6215 valve position sensors. The DV6200 series is equipped with an optional pressure gauge in the shell, as well as an integrated air filter pressure reducing valve, an integrated limit switch, and an integrated valve position transmitter. Another DVC6200SIS is specifically certified for use in Safety Instrumented Systems. The positioning control specification of the DVC6200 series is ±0.5% independent linearity.
FISHER Fisher valve positioner: Compared with other manufacturers' intelligent valve positioners, the steady-state air consumption is much larger. The DVC6200 series has three built-in pressure sensors, which are used for the measurement of air supply pressure, output A pressure, output B pressure, and position feedback of the pneumatic amplifier, as well as valve positioner condition monitoring, fault diagnosis and predictive maintenance.
FISHER Fisher Valve Positioners: The DVC6200 Series offers self-calibration and quick field verification, custom features, automatic monitoring and diagnostics. Improve the dynamic response and control of the actuator/control valve by increasing the forward gain (fast response to valve position changes, reducing deadband and delay time) and small loop feedback gain (adjusting overshoot with valve position response speed feedback) Accuracy, in the event of valve position sensor failure, the DVC6200 series can activate pressure feedback to continue control.
