Belimo B313B+TR24-3-T Brass Ball Valve with Floating Control Actuator - 1/2 3-Way 24V

The Belimo B313B+TR24-3-T is a compact control valve assembly combining a 1/2" three-way brass ball valve with a 24-volt floating control actuator. This combination provides reliable modulating control for HVAC hydronic systems including heating, cooling, and changeover applications.

Key Specifications:

• Valve size: 1/2" (DN 15) threaded connections
• Configuration: 3-way diverting/mixing valve
• Flow coefficient (Cv): 4.7
• Valve body material: Brass
• Actuator voltage: 24V AC/DC
• Control type: Floating (non-spring return)
• Actuator running time: Approximately 150 seconds for 90° rotation
• Fail position: Stays in last position (non-spring return)

Features:

• Compact design for space-constrained installations
• Direct mount actuator-to-valve assembly for reliable operation
• Floating control accepts open/close command signals from compatible thermostats and controllers
• Low power consumption during operation
• Suitable for water and water-glycol mixtures in HVAC systems
• Manual override capability for service and commissioning

The TR24-3-T actuator provides consistent torque throughout its 90-degree rotation, ensuring tight shutoff and accurate flow control. Ideal for fan coil units, unit heaters, radiant panels, and other terminal equipment requiring three-way valve control in commercial and industrial HVAC applications.
