Belimo B221+LF24-3 Ball Valve NPT Cv Floating Control - 3/4 2-Way 24 24V

The Belimo B221+LF24-3 is a compact 2-way characterised control valve (CCV) designed for precise flow control in HVAC applications. This brass ball valve features 3/4" NPT threaded connections and delivers a flow coefficient (Cv) of 24, making it suitable for medium flow applications in hydronic heating and cooling systems.

Key Specifications:

• Valve size: 3/4" NPT threaded connections
• Flow coefficient: 24 Cv
• Valve configuration: 2-way ball valve
• Actuator voltage: 24V AC/DC
• Control type: Floating control with spring return
• Control signal: 2-position or floating (3-point)
• Brass construction for durability and corrosion resistance
• Characterized flow for linear control performance

The LF24-3 actuator provides reliable spring return operation, automatically returning the valve to its failsafe position upon power loss. The floating control mode allows for precise modulating control using simple on/off contact closures, making it ideal for integration with thermostats and building automation systems. This valve assembly is fully factory assembled and tested for immediate installation.
