Schneider Electric (Erie) AH24A020 Actuator

The Schneider Electric Erie AH24A020 is a heavy-duty two-position spring return actuator designed for high-performance zone control in hydronic systems. Engineered for 24Vac applications, this normally open powerhead provides reliable high close-off pressure ratings, ensuring tight shut-off against high pump heads. Suited for high temperature environments, the AH24A020 actuator is optimized for use with PopTop series valves, offering a modular design that allows for tool-free installation and easy replacement. This HVAC zone valve actuator features an 18-inch wire lead configuration for flexible field wiring in tight mechanical plenums. Technicians rely on its synchronous motor drive and robust return spring to maintain system balance and prevent thermal bleed. Whether you are performing a Schneider Electric AH24A20 replacement or a new installation, this actuator ensures precise hydronic flow control and long-term mechanical stability in demanding commercial and residential HVACR circuits.

• High Close-Off Capacity: Prevents bypass and leakage in high-pressure hydronic loops.
• Normally Open Operation: Ensures failsafe circulation or specific system bypass logic during power loss.
• PopTop Connection: Facilitates rapid field service and reduces labor time during actuator head replacement.
• High Temperature Rating: Specifically built to withstand the ambient heat of commercial boiler rooms and steam-adjacent piping.
• Reliable Spring Return: Uses a heavy-duty mechanical spring for consistent positioning every cycle.

Is the AH24A020 compatible with all Erie zone valves?
This actuator is designed for the PopTop series valve bodies. Always verify the stroke length and mounting interface match your existing valve body before installation.

Can I use this actuator for a normally closed application?
No, the AH24A020 is a normally open (NO) model. If your system logic requires the valve to be closed when de-energized, you must select the appropriate AG series normally closed counterpart.

What is the purpose of the 18-inch leads on this model?
The extended leads provide extra slack for routing through conduit or junction boxes, which is essential for meeting local electrical codes in commercial 24V HVAC actuator installations.
