Belimo B211+LF120 Ball Valve Cv with Spring Return Actuator - 1/2 2-Way 1.9 120V

The Belimo B211+LF120 is a complete valve assembly combining a compact 1/2-inch two-way ball valve with an electric spring return actuator. This control valve features a 1.9 Cv flow coefficient, making it ideal for precise flow control in small HVAC hydronic systems, radiant heating applications, and general water or glycol control applications.

Key Features:

• 1/2-inch NPT threaded brass ball valve with two-way flow configuration
• 1.9 Cv flow coefficient for precise flow control in smaller systems
• 120V spring return actuator for fail-safe positioning
• On/Off control operation for reliable two-position control
• Durable brass construction suitable for water and glycol solutions
• Compact design for easy installation in tight spaces
• Spring return mechanism ensures valve returns to closed position on power failure

This factory-assembled valve and actuator combination arrives ready to install, eliminating field assembly time and ensuring proper actuator-to-valve matching. The spring return feature provides fail-safe operation, automatically closing the valve during power interruptions to protect system components.
