Schneider Electric (Erie) AH23A020 Actuator

The Schneider Electric Erie AH23A020 Actuator is a veteran-grade solution for hydronic HVAC systems, specifically designed for high-performance zone control. This Erie PopTop actuator features a 24Vac hysteresis synchronous motor that provides two-position (on/off) operation with a reliable spring return fail-safe. Engineered for high close-off (HCO) applications up to 75 psi, the AH23A020 ensures positive shut-off in demand-heavy environments like fan coils, baseboards, and VAV reheat units. The normally open configuration allows for maximum system safety during power loss, while the 18-inch wire leads facilitate efficient electrical integration. Built with a NEMA 1 rated housing and magnetic clutch technology, this motorized valve actuator minimizes gear train wear and extends the service life of the motor. The iconic PopTop design allows for one-handed installation or removal without tools, enabling technicians to mount the head after the valve body is piped in, significantly reducing field labor and commissioning time.

Key Benefits

• High Close-Off Performance: Rated for up to 75 psi, providing superior differential pressure handling compared to general-purpose actuators.
• Tool-Free Installation: The PopTop actuator snaps directly onto the valve body, allowing for rapid replacement or service without breaking the hydronic seal.
• Fail-Safe Reliability: Mechanical spring return ensures the valve returns to the normally open position during power interruptions.
• Versatile Media Compatibility: Suitable for systems using hot water, chilled water, and up to 15 psig low-pressure steam.
• Maintenance Efficiency: Features a manual override lever and position indicator for streamlined field setup and system flushing.

Common Questions

Can the AH23A020 be used with other valve bodies?
This actuator is specifically designed for the Erie VT/VS series valve bodies. It is an "AH" series high close-off actuator and is cross-compatible with most two-position PopTop valve bodies originally utilizing AG or AH actuators.

Does this actuator require manual calibration?
No, the Schneider Electric AH23A020 requires no linkages or calibration. Its synchronous motor and magnetic clutch handle the stroke limits automatically once snapped into place.

What is the maximum fluid temperature for this model?
The AH series actuators are rated for fluid temperatures up to 250°F (121°C) when used in steam applications, which is higher than the standard AG series 200°F rating.
