Smart Valves & Smart Damper Actuators
DAMPER-ACTUATORS

Carrier’s smart valve and smart damper actuators integrate seamlessly with the i-Vu® system providing real-time data for rapid fault detection. Operators receive immediate alerts for failure, sticking, or leaks. Smart valves feature CCV™ technology ensuring precise flow and energy efficiency across various temperatures. Smart damper actuators use Multi-Function Technology (MFT) for precise damper control and efficiency.

Key Features & Benefits

  • Smart devices support serial communications for precise valve / damper position management without consuming physical I/O on the controller 
  • Connect up to 8 smart devices directly to the actuator sub-network (Act Net) bus on any Act Net-enabled Carrier controller, reducing wiring complexity and installation time 
  • Exact position feedback provided to the i-Vu system for diagnostic purposes 
  • Act Net Auto-address configuration provides quick installation 
  • Smart Valve Selector Tool allows for faster product selection 
  • Ideal for AHUs, heating and cooling coils, FCUs, unit ventilators and VAV re-heat coils 
  • Supports analog (2-10V) connections

Smart Valve Features & Benefits

  • 2-way or 3-way valve and actuator combination options
  • Product ranges from 1/2” to 6” nominal valve sizes 
  • Fail-Safe (NO/NC) and Non-Fail-Safe (NO, fail open/ NO, fail closed and NC, fail open/NC, fail closed) rotary actuator types 
  • Multiple CV product options 
  • NPT connections on 1/2” to 3” valve sizes, ANSI 125, 250 flanges on 4” to 6” valve sizes

Smart Damper Actuator Features & Benefits

  • 35 in-lb to 360 in-lb actuator torque ranges1 
  • 24 VAC / VDC external power supply 
  • Quick running, clear position indication, and manual override
