Belimo B210B+LRB24-SR 1/2" 2-Way Characterized Control Valve with Actuator

The Belimo B210B+LRB24-SR is a complete valve and actuator assembly designed for precision HVAC hydronic control applications. This assembly combines a 1/2-inch two-way characterized control valve body (B210B) with an LRB24-SR spring return actuator for reliable modulating control of heating and cooling water flow.

Key Specifications:

• Valve size: 1/2 inch (DN15) two-way threaded brass body
• Flow coefficient (Cv): 1.2 at full open position
• Actuator: LRB24-SR spring return, 24V AC/DC control
• Control signal: 2-10 VDC or 4-20 mA modulating input
• Spring return fail-safe design for normally closed operation
• Rotation: 90-degree characterized control
• Close-off pressure rating appropriate for commercial HVAC systems

Features and Benefits:

• Factory-assembled valve and actuator combination ensures proper matching and reduces installation time
• Characterized control curve provides precise flow modulation throughout the operating range
• Spring return mechanism provides fail-safe positioning during power loss
• Compact design fits in tight mechanical room installations
• Compatible with Belimo control systems and standard BAS interfaces
• Durable brass valve construction for long service life

Ideal for variable flow hydronic systems in commercial buildings, including hot water heating loops, chilled water cooling systems, and heat pump applications. The characterized control valve provides superior performance compared to linear valves in applications requiring precise temperature control.
