Belimo B312+LF24-SR Control Valve with Actuator Cv - 1/2 3-Way 3.0 24V

The Belimo B312+LF24-SR is a complete control valve assembly combining a 1/2-inch 3-way bronze ball valve with an LF24-SR spring return actuator. This compact unit delivers precise proportional control for hydronic HVAC systems with a flow coefficient (Cv) of 3.0, making it ideal for small zone control applications in heating and cooling systems.

Key Specifications:

• Valve size: 1/2 inch (DN15) with NPT threaded connections
• 3-way configuration for mixing or diverting applications
• Flow coefficient (Cv): 3.0
• Spring return actuator for fail-safe operation
• Operating voltage: 24V AC/DC
• Control signal: 2-10V DC proportional control
• Bronze valve body construction for durability
• Direct mount actuator-to-valve assembly

Features and Benefits:

• Spring return mechanism provides automatic fail-safe positioning during power failure
• Proportional 2-10V DC control signal allows precise modulation of water flow
• Compact design simplifies installation in tight mechanical spaces
• Factory-assembled and tested for reliable performance
• Suitable for heating, cooling, and heat pump applications
• Wide operating range accommodates both AC and DC 24V control systems

This valve assembly is designed for professional installation in commercial and residential HVAC systems where reliable, proportional control of hot or chilled water is required. The spring return feature ensures the valve returns to a predetermined safe position when control power is lost, providing critical system protection.
