Unox Electro-Pneumatic Positioner
What is a Rotary Electro-Pneumatic Positioner?
A Rotary Electro-Pneumatic Positioner is a device used to control the position of a pneumatic actuator. It typically consists of a control system that uses electrical signals to adjust the position of the pneumatic actuator, often involving an electric motor and a pneumatic valve. The actuator’s position is controlled by adjusting the airflow to the actuator via the pneumatic valve. The valve position is regulated by the electric motor, which receives signals from the control system.
The control system may be an independent controller or part of a larger system, such as a process control system or a Supervisory Control and Data Acquisition (SCADA) system.
Where is a Rotary Electro-Pneumatic Positioner Used?
Rotary electro-pneumatic positioners are widely used in various industrial and manufacturing applications, including the control of pneumatic actuators on valves, damper actuators, and other process control equipment. They can be used with both spring-return control valves and double-acting actuators.
