Belimo B307B+TFRB24-3 Control Valve Cv Floating - 3-Way 1/2 0.3 24V

The Belimo B307B+TFRB24-3 is a compact 3-way characterized control valve (CCV) designed for precise hydronic control in HVAC systems. This assembly combines a 1/2" brass valve body with a 24V floating control actuator featuring spring return functionality.

Key Specifications:

• Valve size: 1/2" NPT threaded connections
• Flow coefficient (Cv): 0.3
• Configuration: 3-way mixing/diverting valve
• Actuator voltage: 24V AC/DC
• Control type: Floating point or 2-position control
• Spring return for fail-safe positioning
• Brass valve body construction for durability

Features & Benefits:

• Characterized valve design ensures linear flow control throughout the operating range
• Spring return actuator provides automatic failsafe positioning during power loss
• Compact direct-coupled design minimizes installation space requirements
• Floating control allows integration with standard HVAC controllers
• Suitable for chilled water, hot water, and glycol solutions in heating and cooling applications

This valve assembly is ideal for fan coil units, small air handlers, unit heaters, and other terminal equipment requiring precise flow modulation in low-flow hydronic systems.
