Belimo B309+TFRB120 Characterized Control Valve Cv Stainless Steel - 3-Way 1/2 0.8

The Belimo B309+TFRB120 is a complete control valve assembly combining a B309 3-way characterized control valve (CCV) with a TFRB120 spring return actuator. This compact unit is engineered for precise flow control in HVAC hydronic systems.

Valve Specifications:

• 1/2" NPT threaded connections for easy installation
• 0.8 Cv flow coefficient for accurate flow regulation
• Stainless steel trim construction for corrosion resistance and durability
• 3-way configuration for mixing or diverting applications
• Characterized control curve for linear control performance

Actuator Features:

• Universal 100-240V AC power supply for global compatibility
• Spring return mechanism for fail-safe positioning
• 2-position (On/Off) control operation
• Direct coupled to valve for reliable torque transmission
• Suitable for both heating and cooling applications

This pre-assembled valve and actuator combination simplifies installation, reduces commissioning time, and ensures optimal compatibility between components. Ideal for chilled water, hot water, and glycol solution systems in commercial HVAC applications.
