Belimo B350+AFRB24-S 2 Inch 3-Way Characterized Control Valve 57 Cv with 24V Actuator

The Belimo B350+AFRB24-S is a 2-inch NPT characterized control valve (CCV) with integrated spring return actuator, designed for precise flow control in commercial HVAC applications. This 3-way valve configuration features a 57 Cv flow coefficient and stainless steel construction for durability and corrosion resistance.

Key Features:

• 2-inch NPT threaded connections for standard pipe systems
• 3-way valve design for mixing or diverting applications
• 57 Cv flow coefficient for high-capacity systems
• Stainless steel valve body for long-lasting performance
• 24V AC/DC on/off control with spring return actuator
• Spring return failsafe operation returns to default position on power loss
• 2-position control with auxiliary switch for system feedback
• Characterized flow for optimal control performance

This valve assembly combines Belimo's B350 valve body with the AFRB24-S actuator, providing reliable control for heating and cooling coil applications, heat exchangers, and other hydronic systems requiring precise temperature or flow modulation. The spring return mechanism ensures safe positioning during power failures, while the auxiliary switch enables system monitoring and integration.
