International Environmental 71159909 Actuator

The International Environmental 71159909 Actuator is a professional-grade 2-position electric actuator engineered for precise flow control in fan coil unit (FCU) applications. Designed as an OEM replacement part, this 24V normally open actuator (N/O) provides reliable valve positioning to maintain optimal climate control in commercial and residential HVAC systems. Operating at 50/60 Hz with a power consumption of 6.6 Watts, this component ensures efficient electrical performance without straining the control circuit.

This IEC 71159909 model is built to the technical specifications of Schneider Electric (Erie) AG23A060E1, featuring a Class 2 rating and a manual latch for installation and testing convenience. The two-wire 24V AC configuration allows for seamless integration into existing low-voltage control loops. Its robust construction is focused on longevity in high-cycle environments, ensuring the 2-position valve operation remains consistent under varied thermal loads. When replacing legacy actuators, the normally open 24VAC logic of this unit ensures the fluid path remains open upon power loss, a critical consideration for specific fail-safe piping requirements.

Key Benefits:

• Broad Compatibility: Direct OEM replacement for International Environmental Corporation (IEC) fan coil units and compatible with Erie AG23A060E1 specifications.
• Efficient Power Profile: Low-draw 6.6W motor minimizes energy consumption while providing high torque for reliable valve actuation.
• Installation Versatility: Features a manual override latch to allow manual positioning during system commissioning or power outages.
• Enhanced Reliability: Specifically designed for 2-position (On/Off) control, reducing wear compared to modulating alternatives in standard FCU setups.

Common Questions:

Does this actuator replace the normally closed (N/C) version?
No, the 71159909 is a normally open (N/O) actuator. If your system requires the valve to close upon power loss, you must utilize the 71159901 (N/C) equivalent to ensure proper fail-safe logic.

Is this unit compatible with 120V systems?
This is a 24V AC actuator. Connecting it to a 120V or 277V power source will result in immediate electrical failure and potential damage to the control board.

Can I use this actuator on other valve bodies?
This actuator is designed for standard IEC and Erie PopTop series valve bodies. Always verify the stroke length and mounting interface before attempting to install on third-party valves.
