Introduction
The DVC6200 positioner is a state-of-the-art industrial valve positioner widely used in chemical, oil & gas, power generation, and pharmaceutical industries. It employs Dicrotic Valve Control (DVC) technology and a piezoelectric element to achieve fast, precise, and repeatable valve positioning.
Understanding its principle helps engineers and plant operators select the right positioner for their applications and optimize process efficiency.
- Piezoelectric Element Principle
The DVC6200 uses a piezoelectric element, typically made of ceramic or quartz. When an electric voltage is applied:
- The element expands or contracts linearly.
- This mechanical change is directly transferred to the valve stem, enabling high-precision movement.
- Valve Stem and Plug Movement
- The piezoelectric element is connected to the valve stem, which moves the valve plug.
- As the element expands or contracts, it pushes or pulls the stem, controlling fluid flow through the valve.
This mechanism allows fast, precise adjustments of the valve, improving process control and efficiency.
- Positioning Control
- Electric signal amplitude and frequency determine the valve plug’s exact position.
- Adjusting the signal moves the valve plug to the desired point within the valve body.
This feature makes the DVC6200 ideal for applications requiring reliable and repeatable valve control.
- Feedback Control System
- A built-in sensor monitors valve stem movement.
- The system automatically adjusts the piezoelectric signal to maintain accurate positioning.
This closed-loop feedback control ensures consistent performance even in high-demand industrial environments.
- Fast and Precise Movement
Thanks to piezoelectric technology:
- The DVC6200 positioner opens and closes valves quickly.
- High precision reduces overshoot and improves process stability.
- Low energy consumption lowers operational costs.
