Belimo B210B+LRB24-SR Actuator

The Belimo B210B+LRB24-SR is a precision-engineered 1/2-inch 2-way characterised control valve (CCV) and actuator assembly designed for demanding hydronic HVAC applications. This assembly pairs a chrome-plated brass trim valve body with the LRB24-SR non-spring return actuator, delivering a Cv of 1.2 and a robust 45 in-lb torque rating. The integrated tefzel characterized disc ensures a true equal-percentage flow characteristic, preventing hunting and maintaining stable loop control in terminal equipment. Operating on 24VAC/DC, the actuator accepts a 2-10 VDC proportional control signal, providing accurate modulation for chilled or hot water systems up to 600 psi (close-off). Field technicians value the NPT female connections and the brushless DC motor technology, which offers overload protection without the need for limit switches. This Belimo CCV assembly is designed for high-efficiency performance and simplified installation in tight mechanical spaces.

• Equal Percentage Flow: The specialized disc design eliminates temperature fluctuations common with standard ball valves.
• Maintenance-Free Actuation: The LRB24-SR motor requires no maintenance and provides consistent 95-second run times.
• Bubble-Tight Shut-off: Rated for zero leakage, ensuring energy efficiency and preventing ghost flows in the system.
• Adaptable Installation: The compact footprint and universal mounting bracket simplify retrofits in restricted access areas.

What is the maximum fluid temperature rating for this assembly?
The Belimo B210B is rated for fluid temperatures ranging from 0°F to 250°F (-18°C to 120°C), making it suitable for both heating and cooling loops.

Can I manually override the actuator position?
Yes, the LRB24-SR actuator features an external manual override button that allows for manual positioning of the valve during commissioning or power failures.

Is the actuator protected against electronic stalls?
The actuator uses a microprocessor-controlled brushless DC motor that detects end-stops and protects the gears from damage without requiring external switches.
