Belimo B347+AFRB24 2-Inch 3-Way Characterized Control Valve with Actuator

The Belimo B347+AFRB24 is a 2-inch NPT threaded 3-way characterized control valve (CCV) paired with an AFRB24 spring return actuator, designed for precise control of chilled and hot water systems in commercial HVAC applications. This valve assembly features a flow coefficient (Cv) of 29, providing excellent flow capacity for medium-duty applications.

Key Features:

• 2-inch NPT threaded connections for easy installation
• 3-way mixing or diverting configuration for flexible piping arrangements
• Characterized control valve body with stainless steel trim for durability and corrosion resistance
• 24VAC/DC spring return actuator for failsafe positioning
• 2-position on/off control operation
• Flow coefficient (Cv) of 29 for optimal flow control
• Spring return failsafe ensures valve returns to default position on power loss
• Compact actuator design for tight mechanical room installations

This valve and actuator combination is ideal for VAV terminal units, fan coil units, and other HVAC applications requiring reliable on/off control with failsafe spring return functionality. The stainless steel construction ensures long service life even in demanding water quality conditions.
