Belimo B340+AFRB24-S 1.5" 3-Way Globe Valve with On/Off Actuator 24V

The Belimo B340+AFRB24-S is a complete valve and actuator assembly combining a 1.5-inch threaded bronze globe valve with a spring return electric actuator. This 3-way characterized control valve (CCV) features a flow coefficient (Cv) of 37, making it suitable for medium-capacity hydronic HVAC applications including heating and cooling systems.

Key Features:

• 1.5-inch NPT threaded connections for easy installation
• 3-way diverting or mixing valve configuration
• Cv rating of 37 for medium flow applications
• AFRB24-S spring return actuator with 24 VAC power supply
• On/Off control operation for two-position applications
• Spring return functionality provides fail-safe positioning during power loss
• Bronze body construction for durability and corrosion resistance
• Characterized valve design for linear flow control

This valve assembly is designed for use in commercial HVAC systems where reliable, two-position control is required. The spring return feature ensures the valve returns to a predetermined safe position in the event of power failure, making it ideal for critical temperature control applications.
