Replacement Motor, 24V AC

This Z1 series normally closed actuator is a direct replacement for the Caleffi Z111000 and compatible with Z2 and Z3 motorized zone valves. Designed for quick pushbutton installation, this actuator operates on 24V AC at 50/60 Hz with a full-capacity power consumption of 7 VA, making it ideal for commercial and residential HVAC zoning applications. The unit features spring return to closed position operation, ensuring fail-safe performance when power is lost. It includes a micro-switch auxiliary contact with 18-inch leads rated for 24V AC operation (0.0 A minimum, 0.4 A maximum), allowing integration with standard control systems. The actuator connects via a standard 1/2-inch conduit connector (7/8-inch knockout), simplifying installation in existing infrastructure. With a stroke time under 60 seconds and durable construction featuring a polycarbonate base and cover with aluminum base plate, this replacement actuator delivers reliable performance in demanding HVAC environments. The synchronous motor design ensures consistent, repeatable operation across multiple cycling events. Operating reliably across an ambient temperature range of 32 to 125 degrees Fahrenheit (0 to 50 degrees Celsius), this actuator is suitable for both heated and cooled spaces. Its compact design and standard mounting footprint make it a direct drop-in replacement for legacy systems, reducing installation time and cost while maintaining compatibility with existing zone valve configurations.
