The rotary electro-pneumatic positioner is a device developed to control the position of pneumatic actuators. This type of positioner allows highly precise control by adjusting valve positions via electrical signals. The signals sent to the system coordinate the operation of the electric motor and the pneumatic valve, regulating airflow accordingly. As a result, the actuator’s position can be adjusted quickly and reliably. These systems are most commonly used in integration with centralized control systems such as SCADA.

Application Areas and Usage Purposes

Rotary electro-pneumatic positioners have a wide range of applications in industrial automation systems. These devices are commonly used on control valves and damper systems. They can be seamlessly integrated with both spring-return actuators and double-acting pneumatic actuators. They are particularly preferred in process control applications that require high repeatability and accuracy. In addition, they operate with lower energy consumption compared to electrically actuated systems.

Technical Specifications and Safety Standards

Positioners are devices developed in compliance with CE-certified manufacturing standards. With explosion-proof certifications (Ex ia CT6, Ex d BT6), they can be used in high-risk environments. The IP66 protection class provides superior resistance against dust and water. No performance loss occurs under vibrations in the 5–200 Hz range. In addition, the air connection ports are designed to allow installation from any direction.

User-Friendly Design and Ease of Maintenance

System settings can be adjusted manually without the need for part replacement. Very precise control is achieved with a 1/2 split-range adjustment. The unit has a simple structure that is easy to maintain. Thanks to feedback outputs, direct data transmission to automation systems is possible, allowing valve position information to be monitored in real time. With economical energy consumption, operating costs are kept to a minimum.
