Erie By Schneider Electric AH24B020 120V Normally Open High Close-Off Steam Actuator

The Erie By Schneider Electric AH24B020 is a high-performance PopTop series spring return actuator designed specifically for high close-off steam applications in hydronic heating systems. This actuator operates at 120 volts and features a normally open (N/O) configuration with a spring return (S/R) mechanism, making it ideal for zone control in heating systems.

Key Features:

• Normally Open 2-Position (On/Off) operation with general close-off capability
• High temperature rating for steam applications
• 110-120 VAC operation at 50/60 Hz
• 18-inch standard wire leads for flexible installation
• Synchronous motor drive with spring return
• Mounts directly onto valve body without the need for linkages or calibration
• Power operation time: 9 to 11 seconds, Spring return time: 4 to 5 seconds
• Temperature range: 32 to 250°F fluid @ 169°F ambient (0 to 121°C @ 76°C)
• NEMA 1 enclosure rating

The PopTop series valve bodies and actuators provide easy installation for a variety of heating and cooling applications. The valve's actuator can be installed after the valve body has been installed on the fan coil, baseboard or air handler. This design allows for convenient service and replacement without disturbing the piping system. Note: Valve body must be purchased separately.
