Belimo B213B+TFRB24 NPT Brass Ball Valve Cv Spring Return Actuator - 1/2 2-Way 4.7 with 24V

The Belimo B213B+TFRB24 is a complete valve assembly combining a 1/2" NPT brass ball valve with a 24V spring return actuator for on/off control applications. This compact 2-way valve features a flow coefficient (Cv) of 4.7, making it ideal for small to medium flow control in HVAC systems.

Key Features:

• 1/2" NPT threaded brass valve body for corrosion resistance and durability
• 4.7 Cv flow coefficient for precise flow control
• 24V AC/DC spring return actuator with fail-safe positioning
• 2-position on/off control for simple integration
• Spring return function ensures valve returns to safe position on power loss
• Compact design for easy installation in tight spaces
• Suitable for chilled water, hot water, and glycol solutions in HVAC applications

This factory-assembled valve and actuator combination arrives ready to install, eliminating the need for field assembly and ensuring proper torque and alignment. The brass construction provides excellent resistance to corrosion in typical hydronic systems, while the spring return actuator offers reliable fail-safe operation for critical applications.
