Schneider Electric (Erie) AH13B02A Actuator

As a technician in the field, you know that hydronic reliability relies on the right close-off performance. The Schneider Electric Erie AH13B02A Actuator is a professional-grade 120V HVAC replacement motor engineered for high-demand Poptop zone valve applications. Featuring a normally closed configuration and a reliable spring return fail-safe, this 2-position rotary actuator provides the necessary force to maintain system integrity during power cycles. Unlike general-purpose models, the "AH" series is specifically built for high close-off (HCO) scenarios, handling differential pressures up to 75 psi on 1/2" valves to prevent bypass and ghost flow.

Installation is streamlined via the 18" wire leads and the intuitive Poptop mounting system, allowing for quick head replacement without draining the loop. The integrated auxiliary end switch (SPDT) provides a dry contact signal to cycle the circulator pump or boiler once the valve reaches the open position, ensuring efficient sequencing and reduced equipment wear. Built for standard temperature media of 32°F to 200°F, this 120Vac actuator motor is a staple for contractors managing terminal unit controls in both residential and light commercial hydronic systems.

• High Close-Off Force: Designed for high-performance sealing where standard actuators fail to hold against system pressure.
• Fail-Safe Protection: Mechanical spring return ensures the actuator returns the valve to its normally closed position upon loss of power.
• Integrated End Switch: Simplifies control logic by providing a dedicated signal to boilers or pumps for synchronized operation.
• Tool-Free Mounting: The Poptop design facilitates rapid field replacement, minimizing downtime for the end user.
• Robust Connectivity: 18-inch wire leads provide ample length for clean wiring inside junction boxes or terminal units.

What is the difference between AG13 and AH13 actuators?
While both are 120V 2-position actuators, the AH13 series provides higher close-off pressure ratings compared to the standard AG series. Use the AH13 when you are dealing with higher pump heads to prevent valve leakage.

Can I replace just the auxiliary end switch?
No, the internal end switch is a integrated component of the AH13B02A assembly. If the switch fails to prove contact, the entire actuator head must be replaced.

Is this compatible with 3-way valves?
Yes, this actuator can be used on 3-way VT series valve bodies in a normally closed configuration, typically utilized for bypass or diverting applications in hydronic circuits.
