Belimo B313B+TR24-SR Control Valve Cv with Proportional Actuator - 1/2 3-Way 4.7

The Belimo B313B+TR24-SR is a compact control valve assembly combining a 1/2" 3-way brass valve body with an integrated 24V proportional actuator. Designed for hydronic HVAC applications, this valve provides precise modulating control for heating and cooling systems with a flow coefficient (Cv) of 4.7.

Key Features:

• 1/2" NPT threaded connections for 3-way mixing or diverting applications
• 4.7 Cv flow capacity suitable for small zone control and terminal units
• 24V AC/DC proportional control actuator with 2-10 VDC input signal
• Non-spring return (NSR) operation maintains position on power loss
• Direct mount actuator pre-assembled and factory tested
• Brass valve body construction for durability and corrosion resistance
• 90-second nominal running time for precise modulation

This valve assembly is ideal for fan coil units, unit heaters, small air handling units, and other applications requiring accurate proportional control. The integrated design eliminates field assembly requirements and ensures proper actuator-to-valve matching for optimal system performance.
