Belimo B210+LRB24-3 Valve Assembly

The Belimo B210+LRB24-3 is a high-performance 1/2" NPT assembly engineered for precise fluid control in closed-loop hydronic systems. This 2-way Characterized Control Valve (CCV) features a Cv of 1.2 and is built with a forged brass body and Stainless Steel Trim, providing the durability needed for high-pressure commercial environments. The integrated LRB24-3 non-spring return actuator delivers 45 in-lb of torque, operating on 24Vac or 24Vdc for reliable On/Off/Floating control. Field technicians often ask, "How do I wire the LRB24-3 for floating control?" The three-wire connection allows for incremental positioning without the complexity of a spring-return mechanism. Regarding Belimo B210 flow characteristics, the unit utilizes a Tefzel characterizing disc to maintain an equal percentage flow curve, which prevents hunting and stabilizes temperature control. For contractors verifying Belimo B210+LRB24-3 compatibility, this unit is designed for use with air handling units and terminal equipment where bubble-tight shut-off is required to prevent thermal energy waste. This 24V motorized valve ensures long-term performance without common leakage issues.

• 0% Leakage: Characterized ball valve design provides bubble-tight shut-off, improving system efficiency.
• Corrosion Resistance: Stainless Steel ball and stem prevent scaling and premature wear in harsh hydronic conditions.
• Low Power Consumption: The LRB24-3 actuator is designed for energy-efficient operation during long run times.
• Blow-out Proof Stem: Internal EPDM O-rings and a reinforced stem design enhance safety under high static pressures.

What is the maximum fluid temperature for this assembly?
The B210 valve body is rated for chilled or hot water, typically ranging from 0°F to 250°F (-18°C to 120°C). Always verify the specific glycol concentration if using antifreeze additives.

Can the actuator be manually overridden in the field?
Yes, the LRB24-3 features a manual override button on the housing, allowing technicians to position the valve during commissioning or power loss without removing the drive.

How does the "Characterized" disc improve performance?
Unlike standard ball valves, the CCV disc allows the flow to increase gradually, matching the heat exchanger's output requirements and preventing "all-or-nothing" temperature swings.
