Belimo B309+LRB24-3 Valve Assembly

The Belimo B309+LRB24-3 is a high-performance 3-way characterized control valve (CCV) assembly engineered for precise hydronic regulation in demanding HVAC systems. This 1/2 inch NPT valve features a 0.8 Cv rating and is constructed with a stainless steel trim (ball and stem) to ensure long-term reliability in both chilled and hot water applications, including those with up to 60% glycol. The integrated LRB24-3 actuator delivers a robust 45 in-lb torque, supporting on/off and floating point control signals. Designed for versatile field installation, the non-spring return motor operates on 24VAC/DC power, making it a staple for air handling units, fan coil units, and VAV box reheat coils. The specialized characterizing disc provides an equal percentage flow characteristic, effectively eliminating control loop hunting and enhancing the stability of your building automation system. This factory-assembled unit is ready for immediate deployment in variable or constant flow bypass loops.

• Precise Flow Control: The equal percentage flow characteristic ensures linear heat transfer, preventing the common "hunting" issues associated with standard ball valves.
• Durable Construction: Features a stainless steel ball and stem for superior resistance to corrosion and scaling in hydronic loops.
• Efficient Actuation: The LRB24-3 non-spring return actuator draws only 1.5W during operation, optimizing energy consumption across the network.
• High Close-Off Pressure: Rated for a 200 psi close-off, providing reliable shut-off performance in 1/2" piping systems.
• Simplified Wiring: Supports both 24V AC and DC nominal voltage with standard color-coded lead wires for fast contractor installation.

Is the Belimo B309 suitable for steam applications?
No, this CCV assembly is designed specifically for chilled or hot water and glycol solutions. It is not rated for steam service.

Can this 3-way valve be used for diverting or mixing?
The B309 series is typically configured for mixing applications in the return of a coil or for bypass control. Always verify the flow direction arrows on the valve body during installation.

Does the LRB24-3 actuator require a specific mounting orientation?
While the actuator can be mounted in multiple positions, it should never be installed with the motor hanging upside down to prevent moisture accumulation in the housing.
