International Environmental 71159918 Actuator

The International Environmental 71159918 Actuator is a heavy-duty 120V N/C 2-position actuator engineered specifically for high-temperature hydronic fan coil applications. As a genuine IEC OEM replacement part, it ensures seamless integration with International Environmental Corporation (IEC) valve bodies, maintaining the original engineering specifications and AHRI ratings of the unit. This Class F high-temp actuator is designed to withstand elevated ambient temperatures common in ceiling-mounted and recessed HVAC installations, providing reliable two-position control for water flow management. Using the 71159918 IEC actuator prevents the common failure points associated with generic aftermarket alternatives, such as premature thermal degradation of the internal motor or incorrect mounting alignment. For contractors, this normally closed 120V actuator offers a "drop-in" fit that reduces labor time and ensures consistent system performance. Whether you are performing routine maintenance or a full retrofit, this high-authority component is the professional choice for commercial and industrial IEC fan coil unit parts.

• OEM Compatibility: Precision-milled to meet exact International Environmental Corporation factory standards for fit and function.
• Thermal Resilience: Rated for High Temp (Class F) environments, ensuring durability near hot water coils and in confined plenums.
• Operational Reliability: Normally Closed (N/C) logic ensures the valve returns to its safe position upon loss of power.
• Standardized Voltage: Operates on a standard 110/120V AC 50/60Hz power supply for easy integration into existing building automation circuits.
• Installation Efficiency: Features pre-stripped leads to speed up wiring for field technicians.

Is the 71159918 compatible with other valve brands?
This actuator is specifically designed for International Environmental Corporation (IEC) hydronic systems. While it may share similar mounting footprints with some Erie or Taco models, we recommend verifying exact part numbers to ensure proper stroke and torque requirements are met.

What does 'Normally Closed' mean in this context?
In a Normally Closed 2-position actuator, the valve remains in the closed position when there is no power. When 120V is applied, the actuator moves to the fully open position to allow flow through the fan coil.

Can I use this in high-pressure steam applications?
This model is a Hi-Temp actuator designed for radiant and hydronic heating systems. Always check the maximum fluid temperature and pressure ratings of your specific valve body before installation.
