The Honeywell MVN613A0000 Floating NSR 24V Standard Profile Actuator is an HVAC control device that modulates dampers and valves using a floating control signal. Operating on 24V power, it moves components incrementally to regulate airflow and temperature. It is commonly used in air handling units, VAV systems, and terminal boxes to optimize ventilation and climate control. https://www.partshnc.com/fltg-nsr-24v-std-prfl-actr-2
