Belimo B220B+LF24-3 NPT Control Valve with Floating Actuator - 3/4 2-Way 24V

The Belimo B220B+LF24-3 is a compact 2-way characterized control valve (CCV) package designed for precise hydronic flow control in commercial HVAC applications. This assembly combines a 3/4" NPT bronze ball valve body with an integrated LF24-3 spring return actuator for reliable modulating control.

Key Specifications:

• Valve Size: 3/4 inch NPT threaded connections
• Valve Type: 2-way characterized control valve (CCV)
• Flow Coefficient (Cv): 14
• Actuator: LF24-3 spring return, floating control
• Power Supply: 24V AC/DC
• Control Signal: Floating point (2-position or modulating)
• Spring Return: Failsafe spring return to normally closed position
• Valve Body Material: Lead-free bronze construction

Features and Benefits:

• Characterized ball design provides linear flow characteristics for improved control accuracy
• Spring return actuator ensures failsafe valve closure during power loss
• Compact direct-mount design eliminates the need for valve brackets
• Lead-free materials comply with drinking water safety standards
• Floating control compatible with standard HVAC thermostats and controllers
• Low power consumption for energy-efficient operation

Ideal for heating and cooling coil control, mixing applications, and general hydronic system modulation where failsafe normally-closed operation is required. The Belimo B220B+LF24-3 delivers the precision control and proven reliability that Belimo is known for in building automation systems.
