Belimo B316+TFRB120 Characterized Control Valve with Spring Return Actuator - 3-Way

The Belimo B316+TFRB120 is a complete characterized control valve (CCV) assembly combining a 1/2-inch 3-way ball valve with a spring return electric actuator for precise control of hot or chilled water in HVAC systems. This pre-assembled unit features a Cv rating of 16, providing excellent flow capacity with stainless steel ball and stem construction for long-lasting durability.

Key Features:

• 1/2-inch (DN 15) 3-way mixing/diverting valve with female NPT threads
• High flow capacity with Cv 16 rating
• Stainless steel ball and stem with nickel-plated brass body
• TFRB120 spring return actuator with 22 in-lb (2.5 Nm) torque
• Universal voltage: AC 100-240V, 50/60 Hz operation
• On/Off control with 95° angle of rotation
• 75-second running time with spring return fail-safe operation
• Equal percentage flow characteristic for A-port, modified B-port for constant common port flow
• 600 psi body pressure rating with 200 psi close-off pressure
• IP42/NEMA 2 protection rating for reliable performance
• Low power consumption: 3W holding, 5W running
• PTFE seat and EPDM seals for fluid temperatures from 0-250°F (-18 to 120°C)

This valve assembly is ideal for air handling units on heating or cooling coils, fan coil units, unit ventilators, VAV box reheat coils, and bypass loops. The characterized disc provides enhanced control stability and prevents control loop hunting, reducing energy consumption and extending system component life. The spring return actuator ensures fail-safe positioning during power loss, making it perfect for critical HVAC applications and building automation systems.
