Belimo B317B+TR24-3 3-Way Bronze Ball Valve with Actuator 0.75 Inch 4.7 Cv 24V Floating

The Belimo B317B+TR24-3 is a complete control valve assembly combining a 3/4-inch bronze 3-way ball valve with a TR24-3 non-spring return actuator. This compact valve package is designed for precise control of hydronic systems in HVAC applications including heating, cooling, and mixing functions.

Key Specifications:

• Valve size: 3/4 inch (0.75") threaded connections
• Flow coefficient (Cv): 4.7
• Valve body material: Bronze construction for durability and corrosion resistance
• Configuration: 3-way design for mixing or diverting service
• Actuator type: Non-spring return (NSR) with 24V AC/DC power
• Control: 2-position or floating point control (2PO/FLT)
• Rotation: 90-degree ball valve operation

Features and Benefits:

• Factory-assembled valve and actuator combination ensures proper matching and reduces installation time
• Non-spring return design maintains position during power loss
• Floating control allows proportional positioning based on controller signal duration
• Bronze body provides reliable performance in commercial HVAC water applications
• Compact design suitable for space-constrained mechanical rooms and equipment

This valve assembly is ideal for zone control, mixing applications, and changeover functions in chilled water, hot water, and glycol systems operating within standard HVAC temperature and pressure ranges.
