Belimo B348+AFRB24-SR 2-Inch 3-Way Characterized Control Valve with Actuator

The Belimo B348+AFRB24-SR is a comprehensive characterized control valve assembly combining a 2-inch 3-way brass valve body with an AFRB24-SR proportional actuator. This assembly is engineered for precise modulating control in commercial HVAC hydronic systems, providing reliable performance for heating and cooling applications.

Key Features:

• 2-inch NPT threaded connections for standard piping integration
• 3-way valve configuration for mixing or diverting service
• 37 Cv flow coefficient for accurate flow capacity sizing
• Characterized control disc for linear control characteristics
• 24V AC/DC actuator with spring return fail-safe operation
• 2-10 VDC proportional control signal input
• Factory-assembled and tested valve/actuator combination
• Brass valve body with stainless steel trim for corrosion resistance
• Direct-mount actuator design eliminates separate linkage requirements

This characterized control valve assembly is ideal for variable flow systems, heat exchanger control, and bypass applications. The spring return actuator provides fail-safe positioning during power loss, returning the valve to its normally closed or normally open position depending on system requirements. The proportional 2-10 VDC control signal allows precise modulation for optimal temperature control and energy efficiency.
