Belimo B310B+TFRB24-3 1/2" Three-Way Control Valve 1.2 Cv 24V Floating

The Belimo B310B+TFRB24-3 is a compact 1/2-inch three-way brass control valve assembly designed for HVAC hydronic applications. This valve features a 1.2 Cv flow coefficient, making it suitable for precise flow control in small to medium-sized heating and cooling systems.

Key Features:

• 1/2-inch NPT threaded connections for easy installation
• Three-way mixing or diverting configuration for flexible system design
• 1.2 Cv flow coefficient for accurate flow modulation
• 24V floating control with spring return actuator (TFRB24-3)
• Two-position or proportional floating control capability
• Brass valve body construction for durability and corrosion resistance
• Spring return function ensures fail-safe operation during power loss
• Compact design ideal for space-constrained installations

This valve assembly is ideal for applications requiring precise temperature control in chilled water, hot water, and glycol-based hydronic systems. The floating control actuator provides reliable modulation without the need for complex wiring, making it a cost-effective solution for zone control, unit ventilators, fan coil units, and small air handling units.
