How Does Electro-Pneumatic Positioner Work?

Electric-pneumatic valve locator is a device that receives DCcurrent signal 4-20mA from the controller or the control system,and theprecisely controls valve opening through pneumatic actuator.

What Is Positioner Feedback?

Positioner feedback is a feature that provides real-time information on the valve’s position, which helps improve accuracy and monitoring in industrial control systems.
