Belimo B309+LRB24-SR 1/2" 3-Way Characterized Control Valve with Actuator

The Belimo B309+LRB24-SR is a complete valve and actuator assembly designed for precision control in HVAC applications. This unit combines a 1/2-inch three-way characterized control valve with an LRB24-SR electronic actuator for reliable modulating control of heating and cooling systems.

Key Specifications:

• Valve size: 1/2 inch NPT threaded connections
• Configuration: 3-way mixing/diverting valve
• Control voltage: 24V AC/DC
• Control signal: 2-10 VDC modulating input
• Cv rating: 0.8 (flow coefficient)
• Actuator type: Non-spring return (NSR) electronic actuator
• Characterized valve design for precise flow control

Features:

• Integrated valve and actuator assembly for quick installation
• Modulating control via 2-10 VDC signal for precise temperature regulation
• Non-spring return actuator remains in last position on power loss
• Characterized valve disc provides linear flow characteristics
• Compact design suitable for tight mechanical rooms and equipment spaces
• Brass valve body construction for durability and corrosion resistance

This valve assembly is ideal for hydronic heating and cooling systems, fan coil units, unit heaters, and other HVAC applications requiring precise flow control. The characterized design ensures optimal control across the full operating range.
