The Fisher DVC2000 valve positioner is a product of Emerson, a globally renowned company with a long - standing reputation for innovation and excellence in the field of industrial automation. Emerson has a rich history of providing high - quality industrial products and solutions, and the Fisher DVC2000 is a testament to its commitment to advancing industrial control technology.
The Fisher DVC2000 is a digital valve positioner that has found extensive applications across multiple industries. In the oil and gas industry, it is used in refineries to control the flow of crude oil, refined products, and various process gases. Its accurate positioning capabilities ensure the smooth operation of distillation columns, reactors, and other critical equipment. In chemical plants, the DVC2000 is crucial for controlling the flow of chemical reactants and products, contributing to the safe and efficient production of a wide range of chemical substances.
In the power generation industry, whether it is in coal - fired, gas - fired, or nuclear power plants, the Fisher DVC2000 is employed to control valves in steam systems, feedwater systems, and cooling water systems. This helps in optimizing power generation efficiency, maintaining stable steam pressures, and ensuring the safe operation of the power plant. It is also widely used in the water and wastewater treatment industry, where it controls valves to regulate the flow of water, chemicals for treatment, and sludge, playing a vital role in providing clean water and proper wastewater treatment.
Features
The Fisher DVC2000 valve positioner mainly accepts an analog input signal of 4 - 20mA direct current, which is a standard signal in industrial control systems. This analog input signal serves as the primary control signal for the positioner, allowing it to accurately position the valve according to the received current value. For example, in a typical industrial process control loop, the control system sends out a 4 - 20mA signal based on the measured process variable (such as flow rate, pressure, or temperature) deviation from the set - point. The DVC2000 positioner then interprets this signal to adjust the valve position.
In addition to the standard 4 - 20mA input, the DVC2000 also has the capability for split - range control. Split - range control enables the positioner to operate over different signal ranges to control multiple valves or perform more complex control strategies. This is useful in applications where different process conditions require different valve - control behaviors. For instance, in a chemical reactor with multiple feed streams, different valves may need to be controlled within different signal ranges to maintain the correct chemical reactions.

Product Overview
Regarding voltage and current limitations, for analog control, the minimum voltage at the instrument terminals must be 8.5V. This ensures the proper operation of the internal electronics of the positioner. When it comes to HART communication, the minimum voltage requirement is 9.0V, as HART communication requires a certain level of electrical energy to transmit and receive data accurately. The maximum voltage that the positioner can handle is 30V direct current, which provides a safety margin to prevent over - voltage damage to the device. The minimum control current is 4.0mA, and it's important to note that if the current drops below 3.5mA, it may cause the microprocessor in the DVC2000 to restart. This is because the microprocessor relies on a stable power supply from the input current to function properly. To protect the internal components from over - current situations, the input circuit of the DVC2000 is designed to limit the current, and it also has reverse - polarity protection. This means that if the input current is connected in reverse, it will not cause damage to the instrument, enhancing its reliability and ease of installation in industrial settings.The output signals of the Fisher DVC2000 valve positioner are pneumatic signals that are used to drive the valve actuator. The pneumatic signal range for the output is designed to meet the requirements of various valve actuators.This wide range of output pressures allows the DVC2000 to be compatible with a diverse set of valve actuators, from those with low - pressure requirements to high - pressure - rated actuators.
