Chinese control valve manufacturers offer the following stock of valve positioners and accessories:
Valve positioners are essential devices that play a critical role in the operation and performance of pneumatic control valves. In this article, we will discuss the main features and working principle of valve positioners.
One of the main features of valve positioners is the high-precision adjustment capability. With the help of microprocessing technology, intelligent valve positioners can achieve a perfect balance between signal and feedback, thus providing high-precision adjustment.
Another characteristic of intelligent positioners is their fast response time. These devices can perform actions quickly, making them an ideal solution for applications that require timely response.
Moreover, intelligent valve positioners have an automatic setting function that simplifies the debugging process. This feature saves time and effort while ensuring optimal performance.
Pneumatic valve positioners are known for their high sensitivity to changes in working conditions, making them reliable for adjusting and working stably in time. Additionally, their simple structure makes them easy to maintain and repair.
Furthermore, pneumatic valve positioners have strong adaptability and can work effectively in various pressure ranges. They do not have high requirements for pneumatic control valves, which adds to their versatility.
Lastly, pneumatic valve positioners can be split-range controlled. This means one control signal can control multiple positioners, leading to effective control and improved efficiency.
Pneumatic valve positioners function by converting electrical signals into pressure signals, which control pneumatic control valves. Their core mechanism involves the nozzle flapper and the diaphragm chamber, which sense pressure to adjust the position of the valve stem, resulting in precise control.
