Erie By Schneider Electric AT33A000 24V Non-Spring Return Zone Valve Actuator

The Erie By Schneider Electric AT33A000 is a 24 VAC non-spring return electric actuator with 3-wire floating control signal designed for HVAC zone valve applications. Part of the PopTop series, this actuator provides reliable control for heating and cooling systems in residential and commercial building automation applications.

Key Features:

• Electric floating control with rotary mechanical movement
• Magnetic clutch to maximize the life of the motor and gear train
• Manual operating lever/position indicator facilitates field setup
• Easy to use lever terminal blocks
• Actuator can be installed after the valve body has been installed; mounts directly onto the body without the need for linkages or calibration
• Operating ambient temperature range: 35°F to 125°F (2°C to 52°C)
• NEMA 1 protection rating

Specifications:

• Voltage: 24 VAC
• Power Consumption: 1.0 VA
• Control Type: Floating signal, non-spring return
• Total Run Time: 2 minutes 30 seconds nominal stroke time
• Connection: No factory leads (field-wired)
• UL873 listed (File #E9429); CUL listed for use in Canada

Important Notes:

• Valve must be purchased separately
• 3-wire floating actuators without the time-out option should be used only with controllers that provide time-out
• Compatible with Erie PopTop VT/VS series valve bodies

This actuator is ideal for controlling zone valves in hydronic heating systems, chilled water applications, and other HVAC control applications where precise modulating control is required.
