International Environmental 71488512 24V Normally Closed TACO Actuator for Fan Coil Systems

The International Environmental 71488512 is a 24-volt electric actuator designed specifically for use with TACO zone valves in fan coil and hydronic heating/cooling systems. This genuine OEM replacement actuator provides reliable on-off control for both 2-way and 3-way valve configurations in normally closed (N.C.) applications.

Key Features:

• 24-volt operation for standard HVAC control systems
• Compatible with both 2-way and 3-way valve bodies
• Normally closed (N.C.) configuration - valve remains closed when de-energized
• Designed for TACO valve applications in fan coil units
• Genuine International Environmental OEM part ensures exact fit and reliable performance
• Suitable for closed hydronic heating and cooling systems

This actuator is commonly used in multi-zone HVAC systems, fan coil applications, and hydronic heating systems where precise zone control is required. The normally closed design ensures that the valve automatically closes when power is interrupted, providing fail-safe operation. The compact design allows for easy installation in tight spaces, and the 24V operation integrates seamlessly with standard HVAC control systems.

Applications: Fan coil units, hydronic zone valves, multi-zone heating/cooling systems, baseboard heating, radiant heating, and air handler zone control.
