Belimo B309B+TR24-SR/300 3-Way Bronze Control Valve 1/2" NPT 0.8 Cv with Actuator

The Belimo B309B+TR24-SR/300 is a complete control valve assembly combining a 3-way bronze ball valve with an integrated electronic actuator for precise HVAC flow control applications. This compact unit features 1/2" NPT threaded connections and a flow coefficient (Cv) of 0.8, making it ideal for small-bore hydronic systems requiring accurate temperature and flow regulation.

Valve Specifications:

• 3-way mixing/diverting configuration for hydronic applications
• Bronze body construction for durability and corrosion resistance
• 1/2" NPT female threaded connections
• 0.8 Cv flow coefficient for precise flow control
• Non-spring return (NSR) operation

Actuator Features:

• 24V AC/DC power supply for flexible installation
• 2-10 VDC proportional control signal for modulating control
• Electronic fail-in-place functionality (non-spring return)
• Integrated actuator and valve assembly for space-saving mounting
• Direct mount design eliminates need for additional brackets

This valve assembly is commonly used in chilled water systems, hot water heating applications, fan coil units, and small zone control systems where modulating control is required. The proportional control input allows seamless integration with building automation systems and DDC controllers.
