Belimo B317B+TR24-SR-T 3/4" 3-Way Control Valve Assembly with Actuator | 4.7 Cv | 24V

The Belimo B317B+TR24-SR-T is a complete control valve assembly combining a 3/4" three-way brass ball valve with an integrated TR24-SR-T electronic actuator. This compact control solution is designed for HVAC applications requiring precise modulating control of heating and cooling water in residential and light commercial systems.

Valve Specifications:

• Connection size: 3/4 inch NPT threaded
• Valve type: 3-way mixing/diverting configuration
• Flow coefficient (Cv): 4.7
• Brass construction with chrome-plated ball
• Non-spring return design for fail-in-place operation

Actuator Features:

• Operating voltage: 24 VAC/DC
• Control signal: 2-10 VDC modulating input
• Non-spring return (NSR) operation maintains position on power loss
• Electronic stroke adjustment for precise positioning
• Compact footprint for tight installation spaces
• Manual override capability for service and testing

This factory-assembled valve and actuator combination arrives ready to install, eliminating field assembly time and ensuring proper actuator-to-valve mounting. The 2-10 VDC control interface provides compatibility with modern building automation systems and DDC controllers for accurate proportional control.
