Belimo B351+AFRX24-MFT 2-Inch 3-Way Ball Valve with Actuator | 68 Cv | Spring Return | 24V

The Belimo B351+AFRX24-MFT is a complete valve and actuator assembly featuring a 2-inch NPT 3-way characterized control valve (CCV) paired with a spring return proportional actuator. This assembly is designed for precise control in HVAC hydronic systems where mixing or diverting flow control is required.

Key Specifications:

• Valve Size: 2 inches NPT threaded connections
• Valve Configuration: 3-way ball valve for mixing or diverting applications
• Flow Coefficient (Cv): 68 for high flow capacity
• Valve Body Material: Stainless steel construction for durability and corrosion resistance
• Actuator Type: Spring return (fail-safe positioning on power loss)
• Control Signal: Proportional modulating control (0-10V or 2-10V)
• Power Supply: 24V AC/DC
• Connection Type: MFT (Male Flare Thread) actuator mounting
• Enclosure Rating: NEMA 4/IP54 for outdoor and harsh environment applications

Performance Features:

• Spring return mechanism provides fail-safe operation, returning to default position during power failure
• Proportional control enables precise modulation for accurate temperature control
• Stainless steel valve body offers excellent resistance to corrosive fluids
• NEMA 4 rated actuator protects against dust, dirt, and water splashing from any direction
• Factory assembled and tested for reliable operation and easy installation

This valve assembly is ideal for chilled water, hot water, and glycol solutions in commercial HVAC systems, including fan coil units, air handling units, and radiant heating/cooling applications.
