Belimo B310+TR24-SR-T 1/2" 3-Way Modulating Control Valve 1.2 Cv 24V

The Belimo B310+TR24-SR-T is a compact 1/2-inch three-way characterized control valve (CCV) designed for precise flow control in HVAC hydronic systems. This valve assembly combines a bronze ball valve body with an integrated TR24-SR-T electronic actuator for accurate modulating control.

Key Specifications:

• Valve size: 1/2 inch NPT threaded connections
• Configuration: 3-way mixing/diverting valve
• Flow coefficient (Cv): 1.2
• Actuator type: Non-spring return (non-fail-safe)
• Power supply: 24 VAC/DC
• Control signal: 2-10 VDC modulating input
• Running time: Typically 150 seconds for 90° rotation
• Position feedback: Built-in for precise control

Features and Benefits:

• Characterized control valve design ensures linear flow control throughout the operating range
• Electronic actuator provides accurate modulating control with minimal hysteresis
• Compact integrated design saves installation space and reduces labor
• Non-spring return operation maintains last position on power failure
• Universal 24V power supply works with most building automation systems
• Durable bronze construction for long service life in hydronic applications

This valve assembly is ideal for small zone control, mixing applications in radiant heating systems, fan coil units, and other HVAC applications requiring precise flow modulation in compact installations.
