Schneider Electric (Erie) AH13B020 Actuator

The Schneider Electric (Erie) AH13B020 Actuator is a field-proven 120V PopTop zone valve actuator engineered for precise two-position control in commercial and residential hydronic systems. This spring return unit is designed to return the valve to its normally closed position upon loss of power, ensuring reliable fail-safe operation. As a high close-off (HCO) model, the AH13B020 delivers approximately 25% higher pressure differential capacity compared to general-purpose alternates, making it ideal for high-static hydronic loops and 15 psig steam applications. This hysteresis synchronous motor driven actuator features a one-handed removal mechanism, allowing for rapid servicing without breaking the plumbing line or using specialized tools. Integrated 18-inch wire leads simplify the wiring process within junction boxes. Specifically optimized for the Erie VT/VS series valve bodies, this replacement actuator maintains consistent flow control and 300 psi static pressure integrity across diverse ambient conditions ranging from 32°F to 200°F fluid temperatures.

• Enhanced High Close-Off Performance: Engineered for applications requiring superior shut-off force, preventing leakage in high-head pressure systems.
• Tool-Free Installation: The signature PopTop design facilitates rapid actuator replacement with a simple push-button release, reducing labor time for contractors.
• Reliable Fail-Safe Logic: Mechanical spring return ensures the system defaults to normally closed during power interruptions, protecting equipment and residents.
• Broad System Compatibility: Directly interfaces with Erie VT series and VS series valve bodies for hot water, chilled water, and low-pressure steam.
• Durable Construction: Features a stainless steel base plate and aluminum cover to withstand demanding mechanical room environments.

How do I distinguish between a high close-off and a general close-off Erie actuator?
High close-off models like the AH13B020 are designated by the 'H' in the prefix and are specifically rated for higher differential pressures (up to 75 psi depending on CV) compared to the standard AG series. Always verify the part number on the existing motor housing to ensure the torque matches the system requirements.

Can this 120V actuator be used on a 24V valve body?
Yes, the 120Vac rating refers to the electrical input required to drive the motor. Since the actuator is removable, it can be mounted to any compatible Erie PopTop valve body, provided the body is rated for the fluid temperature and pressure of your specific application.

Does this unit include an end switch for boiler firing?
The AH13B020 is a standard two-wire model without an integrated auxiliary end switch. If your sequence of operations requires a dry contact signal to start a pump or boiler upon valve opening, you would typically require the AH14 series equivalent.
