Belimo B322+LF120 1" 3-Way Control Valve 7.4 Cv with Spring Return Actuator 120V

The Belimo B322+LF120 is a complete control valve assembly combining a 1-inch brass 3-way globe valve with an on/off electric actuator. This pre-assembled unit is designed for hydronic HVAC applications requiring reliable mixing or diverting control of hot or chilled water systems.

Key Specifications:

• 1-inch threaded NPT connections for easy installation
• 3-way valve configuration for mixing or diverting service
• 7.4 Cv (flow coefficient) for efficient flow control
• 120V on/off electric actuator with spring return functionality
• Spring return ensures fail-safe positioning during power loss
• Compact brass valve body for durability and corrosion resistance
• Direct-mounted actuator eliminates coupling alignment issues

Belimo control valves are engineered for commercial HVAC systems including fan coil units, unit heaters, radiant heating/cooling systems, and heat exchangers. The spring return feature provides automatic valve positioning to a safe state during power interruption, making this assembly ideal for applications requiring fail-safe operation. The factory-assembled design ensures proper actuator-to-valve matching and reduces installation time.
