Belimo B310B+LF24-3 1/2" 3-Way Bronze Ball Valve with 24V Floating Actuator

The Belimo B310B+LF24-3 is a compact control valve assembly combining a 1/2" NPT threaded bronze ball valve with an integrated LF24-3 electric actuator. This 3-way valve configuration is designed for hydronic HVAC applications requiring mixing or diverting control of hot or chilled water systems.

Key Specifications:

• Valve size: 1/2" NPT threaded connections
• Flow coefficient (Cv): 1.2
• Valve body: Bronze construction for durability and corrosion resistance
• Actuator voltage: 24V AC/DC
• Control type: Floating control (requires two-position or three-position signal)
• Spring return: Includes spring return mechanism for fail-safe positioning
• Port configuration: 3-way mixing or diverting service

This valve assembly is ideal for zone control, radiant heating systems, fan coil units, and other applications requiring precise modulating control of water flow. The spring return feature ensures the valve returns to a predetermined safe position upon power loss, providing system protection. The compact actuator design allows for installation in tight mechanical spaces while maintaining reliable operation.
