Erie By Schneider Electric AH23A000 PopTop Two-Position Spring Return Valve Actuator 24V

The Erie by Schneider Electric AH23A000 is a high close-off (HCO) two-position spring return valve actuator designed for zone control applications in hydronic heating and cooling systems. This normally open (N.O.) actuator operates on 24 VAC power and features rotary stem movement for reliable valve control in residential and light commercial HVAC applications.

Key Features:

• Two-position on/off control with spring return operation
• High close-off pressure rating for positive shut-off
• Normally open configuration returns to open position when power is removed
• 24 VAC power supply with appliance wire leads
• Rotary mechanical movement for direct valve coupling
• NEMA 1 enclosure rating for general temperature applications
• Part of the Erie PopTop series for easy snap-on installation
• Designed for cycling applications with zone valves

The PopTop design allows the actuator to be easily installed or removed from the valve body without the need for linkages or calibration, making it ideal for retrofit applications on fan coil units, baseboards, and air handlers. When powered, the actuator moves to the closed position, tensing the spring return system. When power is removed, the spring automatically returns the actuator to its normal open position, ensuring fail-safe operation.
