Description
International Environmental 71488512 — 24V Normally Closed Taco Actuator
The International Environmental 71488512 is a 24-volt, normally closed (N.C.) actuator engineered for use with Taco zone valves in hydronic heating and cooling systems. Compatible with both 3-wire and 2-wire configurations, this actuator provides flexible installation options to suit a wide range of residential and light commercial hydronic zoning applications.
Key Features
- 24V operating voltage for compatibility with standard low-voltage hydronic control systems
- Normally closed (N.C.) design ensures the valve defaults to the closed position upon loss of power — enhancing system safety
- Dual-wiring compatibility: supports both 3-wire and 2-wire zone valve configurations
- Designed as a direct replacement actuator for Taco zone valves
- Reliable electrothermal actuation for precise zone flow control
- Compact design for easy installation in tight mechanical spaces
Application
Ideal for hydronic zoning systems in residential and light commercial buildings, this actuator controls the flow of hot or chilled water through individual zones. Its normally closed configuration ensures no flow occurs when the zone is not calling, improving system efficiency and preventing unwanted heat or cooling delivery.
