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

The Belimo B310B+LF24-SR-S is a compact control valve assembly combining a 1/2" three-way bronze ball valve with an LF24-SR-S electronic actuator. This assembly features a 1.2 Cv flow coefficient and is designed for precise control in HVAC hydronic applications including heating, cooling, and domestic hot water systems.

Key Features:

• Three-way bronze ball valve construction with 1/2" NPT threaded connections
• 1.2 Cv flow coefficient for accurate flow control
• 24V AC/DC electronic actuator with spring return functionality
• 2-10 VDC proportional control signal for modulating applications
• Lead-free compliant construction meeting NSF/ANSI 372 standards
• Auxiliary switch for status indication and system integration
• Fail-safe spring return to default position on power loss
• Compact design for space-constrained installations

This valve assembly is ideal for hydronic mixing and diverting applications in commercial HVAC systems, providing reliable modulating control with the safety of spring return operation. The integrated auxiliary switch enables BAS integration for remote monitoring and control.
