Belimo B308+LF24-SR 1/2" 3-Way Ball Valve with LF24-SR Actuator

The Belimo B308+LF24-SR is a compact 1/2" three-way brass ball valve assembly designed for precision control in hydronic HVAC systems. This factory-assembled unit combines the B308 bronze ball valve body with the LF24-SR spring return actuator for reliable modulating control applications.

Key Features:

• 1/2" NPT threaded connections for easy installation
• Three-way valve configuration for mixing or diverting applications
• 0.46 Cv flow coefficient for proper system sizing
• 24V AC/DC actuator with spring return for fail-safe positioning
• 2-10 VDC proportional control signal for precise modulation
• 35 in-lb actuator torque for positive shutoff
• Compact design suitable for space-constrained installations
• Bronze/brass construction for durability and corrosion resistance

This valve assembly is ideal for chilled water, hot water, and glycol solutions in commercial building automation systems. The spring return function ensures the valve returns to a predetermined safe position upon power loss, making it suitable for safety-critical applications. The 2-10 VDC control interface allows for seamless integration with building management systems and DDC controllers.
