With the advancement of smart instrumentation technology, microelectronics has been widely integrated into conventional instruments, significantly enhancing their functionality and performance. The valve positioner is a key accessory for control valves and is typically used in conjunction with pneumatic control valves. It receives the output signal from the controller and uses this signal to regulate the pneumatic control valve. Once the control valve actuates, the displacement of the valve stem is fed back to the valve positioner via a mechanical linkage, and the valve position information is transmitted as an electrical signal to the higher-level control system.

When manual operators, PID controllers, DCS systems, or PLCs use pneumatic control valves to perform process control, it is necessary to convert electrical signals into pneumatic signals in order to operate the pneumatic actuators. Electrical transducers and electric valve positioners both serve this function; however, because these two types of instruments differ in structure and function, their applications also vary.

Under the advancement of technology, we have developed a valve positioner to control the equipment in order to work more accurately. The valve positioner can be used in conjunction with various equipment. Using the valve positioner, we can understand a signal of the adjustment output in the equipment, so as to realize the control of the equipment. Although the use of valve positioners is very common in our lives, many people do not know much about the structure and working principle of valve positioners. Let's take a look at the working principle of the valve positioner together.
