Schneider Electric (Erie) AP33A000 Actuator

The Schneider Electric (Erie) AP33A000 Actuator is a high-performance, non-spring return HVAC valve actuator designed for professional-grade modulating control in commercial hydronic systems. This 24VAC component belongs to the Erie PopTop series, widely recognized by contractors for its "snap-on" design that allows for rapid actuator replacement without draining the system or breaking pipe connections. As a 24VAC proportional actuator, the AP33A000 provides field-selectable control signals, supporting 0-10 VDC, 0-5 VDC, 5-10 VDC, and 4-20 mA inputs. This flexibility makes it a primary choice for building automation systems (BMS) requiring precise flow regulation in fan coil units, baseboard radiation, and small air handlers. Unlike spring-return models, this unit maintains its last position upon power loss, making it ideal for non-safety-critical applications where energy efficiency and stable positioning are prioritized. Its robust synchronous motor and high-temperature plastic housing ensure long-cycle reliability in environments with ambient temperatures up to 125°F.

Key Benefits for Professional Installation

• Tool-Free Mounting: The PopTop quick-release mechanism facilitates immediate installation onto 1/2" through 1-1/4" Erie valve bodies, significantly reducing labor hours during retrofits.
• Universal Signal Compatibility: Field-selectable jumpers allow the AP33A000 to integrate with various DDC controllers using standard 0-10VDC or 4-20mA analog outputs.
• Manual Override: Features an integrated lever for manual positioning, allowing technicians to verify flow and bypass controls during commissioning or troubleshooting.
• Sync Motor Precision: Designed without a time-out feature, providing consistent 150-second full-stroke timing for high-resolution proportional valve control.
• Durable Core: Engineered for media temperatures up to 200°F, supporting both chilled water and hot water systems with up to 50% glycol concentrations.

Common Questions & Technical Support

Is the AP33A000 a spring return actuator?
No, the AP33A000 is a non-spring return (NSR) actuator. In the event of a power failure, the valve will remain in its last commanded position. For applications requiring a fail-safe open or closed state, a spring-return model from the Erie series should be utilized.

Can I use this actuator with a 4-20mA control signal?
Yes. This Schneider Electric actuator is compatible with 4-20mA proportional signals. Technicians must ensure the internal jumpers are correctly set to the current-based input before wiring to the terminal block.

How do I verify compatibility with my existing valve body?
The AP33A000 is designed specifically for Erie VM series PopTop valve bodies. It is compatible with 2-way and 3-way configurations. Check for the distinctive mounting pins on your valve body to ensure it is a "PopTop" style connection before ordering.
