Belimo B311B+TFRB24-SR : 3-Way 1/2" Characterized Control Valve (CCV), Cv Rating 1.9, (3.8 GPM @ Δ 4 psi), Chrome Plated Brass Trim + Fail-Safe Valve Actuator, 24VAC/DC, Modulating 2-10VDC Control Signal, 5-Year Warranty

Ideal for air handling units, fan coil units, and various HVAC applications, the Belimo CCV ensures efficient heating or cooling coil regulation. Its versatility extends to Unit Ventilators, VAV box re-heat coils, and bypass loops, making it a cornerstone of hydronic systems with variable flow requirements.

Key Benefits of the Belimo Characterizing Disc:

  • Equal percentage flow characteristic for precise control.
  • Enhanced control stability with the characterizing disc.
  • Comparable Cv values to globe valves of the same size.
  • Reduced need for multiple pipe reductions.
  • Prevents control loop "hunting," ensuring longevity of components and optimizing energy consumption.
