Schneider Electric (Erie) AH23B020 Actuator

The Schneider Electric (Erie) AH23B020 Actuator is a high-performance, 120Vac motorized drive designed for direct mounting on VT/VS series zone valves. This PopTop actuator features a two-position, synchronous motor design with a spring return fail-safe, ensuring the valve returns to its normally open position during a power loss. Engineered for demanding hydronic environments, it provides high close-off pressure capabilities, making it an ideal choice for fan coils, baseboards, and AHUs where reliable fluid control is critical. The unit includes 18-inch wire leads for streamlined electrical integration and a magnetic clutch to protect the gear train, extending the mechanical life of the 110/120V motor. Its unique one-handed "PopTop" engagement allows for rapid installation or removal without the need for complex linkages or field calibration across various heating and cooling applications.

• High close-off performance: Specifically designed to handle increased differential pressures in closed hydronic systems and up to 15 psig steam.
• Fail-safe reliability: Integrated spring return mechanism automatically drives the valve to a normally open state if power is interrupted.
• Simplified maintenance: The signature PopTop design enables "snap-on" installation, allowing you to replace the actuator without draining the system or removing the valve body.
• Durable construction: Features a stainless steel base plate and aluminum cover to withstand the temperature rigors of HVAC zone valve environments.
• Universal Compatibility: Operates on standard 120Vac power and interfaces easily with most 2-position (on/off) building automation controllers.

Can this actuator be installed on a 3-way valve?
While the AH23B020 is primarily used with 2-way normally open configurations, it can be applied to 3-way valve bodies to provide normally open flow depending on the body porting and orientation.

Is calibration required after installing the PopTop motor?
No, the Schneider AH23B020 is a "fit and forget" component. The drive mechanism is self-aligning and does not require manual linkage adjustments or specialized calibration tools.

What indicates the valve position?
This model utilizes a mechanical position indicator on the housing, allowing technicians to verify whether the system is in the open or closed state during 120V operation.
