Valve positioners have several key features, including high-precision adjustment, fast response, automatic setting, high sensitivity, simple structure, and strong adaptability. These features are essential in ensuring that the valve meets the required degree of accuracy and stability in various working conditions.
Intelligent valve positioners, in particular, employ microprocessing technology to achieve high-precision adjustment, which ensures a perfect balance between signal and feedback. They also have the characteristic of fast response, which allows quick actions and adjustments. Moreover, intelligent positioners can be automatically set up, which greatly simplifies the debugging process.
Pneumatic valve positioners offer excellent sensitivity to changes in working conditions and can adjust and work stably in real-time. With their simple structure, they are relatively easy to maintain and repair. Additionally, pneumatic valve positioners have strong adaptability, making them suitable for various pressure ranges.
Pneumatic valve positioners employ a working principle that involves converting electrical signals into pressure signals to control pneumatic control valves. The core mechanism includes the nozzle flapper and the film chamber, which perform pressure sensing to adjust the position of the valve stem, thereby achieving precise control.
Another benefit of pneumatic valve positioners is their split-range control function. One control signal can control multiple positioners, which is an added advantage in automating various processes.
