The Honeywell MP918A1024 actuator primarily serves as a pneumatic damper actuator, facilitating effective airflow control in various applications. This device allows for push-on barb air connections measuring either 5/32 inches for pilot air or 1/4 inches. Its operational capacity is rated at a maximum pressure of 25 psi, ensuring effective performance.

Equipped with a positive positioner, this actuator features a spring range of 10 psi, enhancing its versatility in adjusting airflow as needed. The fail-safe mode is designed for spring return, allowing the actuator to default to a safe position in the event of power loss or system failure, thereby enhancing operational safety.

The actuator generates high force levels during operation, making it efficient for controlling larger dampers. The stroke length measures 3 1/2 inches, providing ample movement for effective air regulation.

Operating temperatures for the MP918A1024 unit span from a minimum of -29 °C to a maximum of 70 °C, allowing it to function widely under different climatic conditions. Furthermore, it is designed to work optimally in environments with relative humidity levels ranging from 5% to 95% without condensation affecting its performance.
