International Environmental 71488515 Actuator

The International Environmental 71488515 Actuator is a professional-grade, 120-277v NC 2w actuator designed for precise flow control in commercial HVAC applications. Engineered as a two-position thermal actuator, this component provides reliable normally closed (NC) operation, ensuring the valve remains seated during power loss or idle states. The 71488515 is the direct replacement for 71488503, offering a streamlined upgrade path for technicians servicing older terminal unit control valves or fan coil unit (FCU) actuators. With a universal voltage rating and a 700 mA current draw, this IEC replacement actuator simplifies inventory by covering a broad range of field requirements. Its high-torque performance and 96-inch wire lead allow for flexible installation within tight cabinet spaces, maintaining consistent system pressure and temperature regulation without the mechanical failures common in non-OEM alternatives. This 2-way normally closed actuator is the standard for maintaining peak efficiency in International Environmental Corporation (IEC) hydronic systems.

• Universal Voltage Compatibility: Operates efficiently across 120V to 277V AC, reducing the need for multiple SKUs on the service truck.
• Direct Drop-in Replacement: Specifically designed to replace the obsolete 71488503 actuator with identical mounting and electrical specs.
• Enhanced Durability: Thermal-style operation eliminates gear noise and mechanical wear, extending the service life of the valve assembly.
• Normally Closed Logic: Provides a fail-safe "closed" position to prevent unintended heating or cooling during power interruptions.

Is the 71488515 compatible with 120V fan coil systems?
Yes, this actuator is rated for 120-277v, making it a versatile choice for both 120V and 277V fan coil unit applications.

Does this part replace the B035-71488503?
Correct. The 71488515 is the official successor and direct replacement for 71488503, ensuring full mechanical and electrical compatibility.

What is the default state of this actuator?
This is a normally closed (NC), 2-wire actuator, meaning the valve remains closed until power is applied by the controller.
