Belimo B212B+LRB24-SR 1/2" Characterized Control Valve with Actuator

The Belimo B212B+LRB24-SR is a complete valve and actuator assembly designed for precise control of hydronic heating and cooling systems. This compact package combines a 1/2" two-way characterized control valve with an LRB24-SR spring return actuator for reliable modulating control in HVAC applications.

Key Specifications:

• Valve size: 1/2" NPT threaded connections
• Flow coefficient (Cv): 3.0 for excellent flow capacity
• Actuator: 24V spring return, normally closed (fail-safe closed position)
• Control signal: 2-10 VDC modulating input for proportional control
• Characterized ball valve design for linear flow control
• Spring return for fail-safe operation during power loss
• Direct mount actuator assembly, factory tested

This valve assembly is ideal for small to medium flow applications including fan coil units, unit heaters, radiant heating systems, and hydronic zone control. The characterized ball design provides superior control characteristics compared to standard ball valves, while the spring return actuator ensures the valve closes automatically during power failure for system protection.
