Belimo B317B+TR24-SR/300 3/4" 3-Way Bronze Control Valve with Actuator, 4.7 Cv, 24V, 2-10V Modulating

The Belimo B317B+TR24-SR/300 is a complete valve and actuator assembly designed for precise modulating control in HVAC hydronic systems. This 3-way bronze valve features a 3/4" NPT connection size with a flow coefficient (Cv) of 4.7, making it ideal for small to medium commercial applications requiring accurate temperature or flow control.

Key Specifications:

• Valve Body: 3/4" NPT, 3-way configuration, bronze construction for durability and corrosion resistance
• Flow Capacity: 4.7 Cv rating for optimal flow control
• Actuator Type: TR24-SR non-spring return (NSR) electric actuator
• Power Requirements: 24 VAC/DC operation
• Control Signal: 2-10 VDC proportional modulating control for precise positioning
• Run Time: 300 second full stroke (5 minutes)
• Application: US Close Coupled Valve (CCV) configuration with actuator directly mounted to valve

This non-spring return actuator maintains valve position during power failure, making it suitable for mixing and diverting applications in chilled water, hot water, and glycol systems. The proportional 2-10 VDC control input allows for seamless integration with modern building automation systems and DDC controllers.

Typical Applications: Fan coil units, unit heaters, air handling units, heat exchangers, and other hydronic HVAC equipment requiring modulating 3-way valve control.
