Belimo B212B+LF120-S 1/2" Brass Ball Valve with Actuator 120V On/Off

The Belimo B212B+LF120-S is a complete valve and actuator assembly designed for two-way on/off control in HVAC applications. This compact package combines a 1/2" brass ball valve body with an LF120-S non-spring return electric actuator, providing reliable control for heating, cooling, and domestic water systems.

Valve Specifications:

• Connection size: 1/2" threaded female NPT
• Flow coefficient (Cv): 3.0
• Two-way ball valve design
• Brass construction for durability and corrosion resistance
• Suitable for water, glycol solutions, and neutral fluids

Actuator Features:

• Operating voltage: 120V AC
• Control type: On/Off (two-position)
• Spring return for fail-safe operation
• Auxiliary switch for status indication
• Quick mounting directly to valve body
• Low power consumption

This pre-assembled valve and actuator combination eliminates field assembly and ensures proper actuator-to-valve matching. The spring return feature provides automatic valve positioning during power failure, enhancing system safety. The integrated auxiliary switch enables remote position monitoring for building automation systems.
