Belimo B313B+LF24-SR-S Bronze Ball Valve with Actuator - 1/2 3-Way 24V

The Belimo B313B+LF24-SR-S is a lead-free bronze ball valve assembly designed for precise control in HVAC hydronic systems. This compact valve features a 1/2" connection size with a 3-way configuration and 4.7 Cv flow coefficient, making it ideal for mixing and diverting applications in heating and cooling circuits.

Valve Specifications:

• Lead-free bronze construction for potable water compliance
• 3-way valve configuration for mixing or diverting service
• 4.7 Cv flow coefficient for optimized flow control
• 1/2" NPT threaded connections
• Characterized control valve (CCV) for linear control performance

Actuator Features:

• 24V AC/DC low voltage operation for safe installation
• Spring return mechanism for fail-safe positioning on power loss
• 2-10 VDC modulating control signal input
• Auxiliary switches for position indication and system integration
• Direct mount coupling for secure valve-actuator connection

This valve assembly combines Belimo's reliable actuator technology with durable brass valve construction, providing accurate proportional control for chilled water, hot water, and glycol-based heating/cooling systems. The spring return feature ensures the valve returns to a predetermined position during power failure, adding critical safety functionality to commercial HVAC applications.
