Belimo B210+TR24-SR 1/2" 2-Way Characterized Control Valve with Actuator

The Belimo B210+TR24-SR is a compact 1/2-inch two-way characterized control valve (CCV) assembly designed for precise proportional control in HVAC hydronic systems. This factory-assembled unit combines a brass valve body with a non-spring return electric actuator for reliable modulating control of hot or chilled water flow.

Key Specifications:

• Valve size: 1/2 inch NPT threaded connections
• Flow coefficient (Cv): 1.2
• Valve type: 2-way characterized control valve
• Actuator voltage: 24V AC/DC
• Control signal: 2-10 VDC proportional
• Spring return: Non-spring return (NSR) for fail-in-last-position
• Running time: Typically 150 seconds

Features:

• Characterized flow for linear control performance
• Non-spring return actuator maintains valve position on power loss
• Proportional 2-10 VDC control for precise modulation
• Compact design for space-constrained installations
• Factory-assembled and tested for plug-and-play installation
• Brass valve body for corrosion resistance

Ideal for small zone control, fan coil units, unit heaters, and other HVAC applications requiring precise flow control. The non-spring return design is suited for applications where maintaining the last position during power outages is preferred over returning to a fail-safe position.
