Belimo G765+AFX24-MFT-X1 Valve Assembly

The Belimo G765+AFX24-MFT-X1 is a high-performance 3-way flanged globe valve assembly designed for demanding chilled water, hot water, and low-pressure steam applications in large air handling units. This 2-1/2 inch valve features a robust cast iron body with bronze trim and a 68 Cv rating, ensuring precise linear flow control for complex hydronic systems. The assembly is powered by the AFX24-MFT-X1 spring return actuator, delivering 180 in-lb of torque for fail-safe operation. Utilizing Multi-Function Technology (MFT), this unit supports a wide range of control signals, including 4-20mA (via 500 Ohm resistor), PWM (1500 Ohm), floating point, and on/off configurations. Operating on 24Vac/dc, the system provides high-resolution feedback and customizable run times, making it a standard choice for contractors integrating building automation systems that require reliable diverting or mixing functionality.

• Multi-Function Technology: Provides field-programmable control for modulating, on/off, or floating point signals to match specific site requirements.
• Fail-Safe Reliabilty: Features a mechanical spring return mechanism that ensures the valve returns to a safe position during power loss.
• Durable Construction: Built with an ANSI Class 125 flanged cast iron body and a stainless steel stem for long-term service in HVACR environments.
• Precision Control: A high 68 Cv and linear flow characteristic allow for accurate temperature regulation in large-scale coils.
