Belimo B212B+LF24-SR-S NPT Control Valve with Actuator Cv - 1/2 2-Way 3 24V

The Belimo B212B+LF24-SR-S is a complete control valve assembly combining a 1/2" NPT two-way brass ball valve with an LF24-SR-S proportional actuator. This compact assembly is designed for precise control of heating, cooling, and domestic hot water systems in commercial HVAC applications.

Valve Specifications:

• Valve body: 1/2" NPT threaded brass construction
• Configuration: 2-way characterized control valve (CCV)
• Flow coefficient (Cv): 3.0 for accurate flow control
• Chrome plated brass ball with EPDM seals
• Close-off rating suitable for HVAC zone control

Actuator Features:

• 24V AC/DC proportional control actuator
• Spring return for fail-safe positioning (returns to closed position on power loss)
• Control signal: 2-10 VDC modulating input
• Includes auxiliary switch (SW) for position feedback
• Running time: 150 seconds for 90° rotation
• Direct-coupled design for reliable operation

This pre-assembled valve and actuator combination eliminates field assembly time and ensures proper actuator-to-valve matching. The spring return feature provides automatic shutdown protection, while the proportional control enables precise modulation for optimal temperature control and energy efficiency. Ideal for chilled water, hot water, and heating/cooling coil applications.
