Duff Norton MPD6405-12 Linear Actuator 12" Stroke 12 VDC 500 PSI

The Duff Norton MPD6405-12 Linear Actuator is a 12-inch stroke electromechanical motion component operating on a 12 VDC power supply with a 500 PSI load capacity rating, designed for controlled linear movement. It works by converting electrical input into precise forward and reverse stroke motion through an internal drive mechanism that extends and retracts the actuator shaft. In HVAC system applications, it is used within dampers, valve assemblies, and positioning mechanisms where accurate movement control is required for airflow or fluid regulation. It is mounted to the target assembly and connected through control wiring to enable coordinated motion within system operation.
