Belimo B214B+TFRB120 Ball Valve Cv with Spring Return Actuator - 2-Way 1/2 7.4

The Belimo B214B+TFRB120 is a complete valve assembly combining a 1/2" 2-way characterized control valve (CCV) with a spring return electric actuator. This compact assembly delivers precise flow control in HVAC systems with a flow coefficient (Cv) of 7.4, making it ideal for small zone control applications, fan coil units, and hydronic heating or cooling systems.

Key Features:

• 1/2" NPT threaded brass ball valve with characterized flow design for optimal control
• 7.4 Cv flow coefficient for accurate flow regulation in smaller applications
• Universal 100-240V AC power supply for international compatibility
• Spring return mechanism provides fail-safe operation, returning to closed position on power loss
• On/Off (2-position) control for simple open/close operation
• Factory-assembled and tested for reliable performance
• Compact design minimizes installation space requirements

The spring return feature ensures automatic valve closure during power interruptions, making this assembly suitable for safety-critical applications. The characterized ball valve design provides superior flow control compared to standard ball valves, delivering more linear control characteristics throughout the operating range. Belimo's reputation for quality and reliability makes this valve assembly a trusted choice for commercial HVAC contractors and building automation professionals.
