IEC 71488512 24V 3W/2W Normally Closed Taco Actuator

The IEC 71488512 24V 3W/2W Normally Closed Taco Actuator is a highly reliable actuator designed for controlling valves in hydronic and HVAC systems. Operating at 24V, this actuator provides precise control for 3-way or 2-way valves, ideal for water flow regulation in fan coil units, heating, and cooling circuits. Its normally closed configuration ensures fail-safe operation by keeping the valve closed in the event of a power failure.
