Belimo B219B+LF24 3/4" 2-Way Ball Valve with Actuator | 10 Cv | 24V On/Off Spring Return

The Belimo B219B+LF24 is a compact 3/4-inch two-way characterized control valve (CCV) assembly featuring an integrated 24VAC spring return actuator for reliable on/off control in HVAC applications. This bronze valve body assembly delivers a flow coefficient (Cv) of 10, making it suitable for small to medium-sized hydronic systems requiring precise fluid control.

Key Features:

• 3/4-inch NPT threaded connections for standard pipe integration
• Two-way ball valve design with characterized flow control
• 10 Cv flow coefficient for optimized system performance
• 24VAC spring return actuator provides fail-safe positioning
• On/off control function for simple system integration
• Durable brass/bronze construction for long service life
• Direct mount actuator eliminates separate bracket requirements
• Compact footprint for space-constrained installations

This valve assembly combines Belimo's B219B valve body with the LF24 actuator in a factory-assembled package, ensuring proper torque calibration and reliable operation. The spring return mechanism automatically returns the valve to its fail-safe position upon power loss, providing critical safety functionality in heating and cooling applications. Ideal for use in chilled water, hot water, and glycol solutions within specified temperature and pressure ratings.
