Belimo B321+LRB24-3-S Characterized Control Valve with Floating Actuator - 3/4 3-Way

The Belimo B321+LRB24-3-S is a 3-way 3/4" characterized control valve (CCV) with Cv rating of 24, capable of handling up to 48 GPM at 4 psi differential pressure. This assembly combines the B321 valve body with stainless steel trim and the LRB24-3-S non fail-safe actuator operating on AC/DC 24V with on/off floating point control. The valve includes an integrated SPDT auxiliary switch rated at 3A @250V for system integration.

Key Features:

• Equal percentage flow characteristic for precise control
• Enhanced control stability with the characterizing disc
• Stainless steel trim for durability and corrosion resistance
• Non-spring return actuator with floating control signal
• Female NPT threaded connections for easy installation
• Prevents control loop "hunting," ensuring longevity of components and optimizing energy consumption

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 suitable for both constant and variable flow hydronic systems. This assembly is backed by Belimo's 5-year warranty.
