Belimo B309+LF120 Stainless Steel Ball Valve with Actuator NPT - 3-Way 1/2 120V

The Belimo B309+LF120 is a compact control valve assembly combining a 3-way stainless steel ball valve with an LF120 spring return actuator. Designed for HVAC applications requiring reliable on/off control, this valve assembly features 1/2" NPT threaded connections and delivers a flow coefficient (Cv) of 0.8 for precise fluid control in smaller systems.

Key Features:

• 3-way ball valve design for diverting or mixing service
• Stainless steel construction for durability and corrosion resistance
• 1/2" NPT female threaded connections
• 0.8 Cv flow coefficient
• LF120 spring return actuator with 120V AC power
• 2-position on/off control for simple operation
• Spring return to normal position on power failure for safety
• Compact design suitable for space-constrained installations

This valve assembly is ideal for chilled water, hot water, and glycol solutions in commercial HVAC systems. The spring return functionality ensures the valve returns to its fail-safe position during power interruptions, making it suitable for critical control applications where safety is paramount.
