Belimo B208B+LF24-SR-S Control Valve Cv Spring Return - 1/2 2-Way 0.46 24V

The Belimo B208B+LF24-SR-S is a compact 1/2-inch two-way characterized control valve (CCV) designed for precision modulating control in HVAC hydronic systems. This normally closed valve features a 0.46 Cv flow coefficient, making it ideal for small zone control applications, radiant heating/cooling systems, and fan coil units.

Key Features:

• 0.46 Cv flow coefficient for precise flow control in small pipe applications
• 24V actuator with spring return (fail-safe closed) for reliable operation during power failure
• 2-10 VDC proportional control signal for accurate modulation
• Lead-free brass construction compliant with potable water applications
• Integrated actuator and valve assembly for easy installation
• Auxiliary switches (SW) for status indication and monitoring
• Compact design saves installation space in tight mechanical rooms

This actuated control valve assembly combines Belimo's proven valve body technology with their reliable electric actuator platform, delivering precise temperature and flow control for commercial and residential hydronic heating and cooling systems. The spring return mechanism ensures the valve returns to the closed position during power loss, providing fail-safe protection.
