Description
The Honeywell MVN643A0000 Control Valve Actuator that operates in two positions, and it is ideally used in HVAC systems. It is powered at 24 VAC and produces a torque of 27 in-lb to control valves that modulate air or fluid flow in the system. This actuator has fail-safe non-spring return capability, which means that the valve position remains unaltered in the case of power failure. This is used in the various HVAC components such as the dampers, valves, and the mixing boxes to allow control of airflow in HVAC systems.
