Belimo B210B+TR24-SR/300 1/2" NPT 2-Way Control Valve with Actuator 24V 2-10V Proportional

The Belimo B210B+TR24-SR/300 is a compact 2-way brass control valve assembly designed for precise flow control in HVAC applications. This complete package combines a 1/2" NPT threaded brass valve body with an integrated TR24-SR proportional actuator for reliable modulating control.

Key Specifications:

• Valve size: 1/2" NPT threaded connections
• Flow coefficient (Cv): 1.2
• Valve type: 2-way brass construction
• Actuator: TR24-SR non-spring return (NSR)
• Power supply: 24V AC/DC
• Control signal: 2-10V DC proportional
• Close-off pressure rating: Up to 300 PSI

Features and Benefits:

• Non-spring return actuator provides fail-in-place operation for energy efficiency
• Proportional 2-10V control enables precise modulation for optimal temperature control
• Compact brass valve body suitable for space-constrained installations
• High close-off pressure capability ensures tight shutoff
• Factory-assembled and tested for reliable performance
• Compatible with standard building automation systems

Ideal for use in chilled water, hot water, and hydronic heating/cooling systems where proportional flow control is required. The non-spring return design maintains valve position during power loss, reducing energy consumption in typical HVAC applications.
